Nowadays, some people call the young monks "Lok ta" (maybe from the habit), some call Lok mchas (from pitaka), and some call Lok Bong (venerable older brother) or Lok p-oun (venerable younger brother) because of their age.

Norum, only uneducated and not informed people do so, its actually very respectless, since age is no matter in regard of pabbajitās and virtuose people. Its very usuall today, put do not follow, since such way of adressing shows that one does not have really faith in the tripple gems.
As the Buddha told, there are 4 thongs one should be careful of, even if young and small: a fire, a snake, a young soldier from good family and a young recluse.
Dahara Sutta: Jung So a properway, even if just 8 years, is to adress with "degun" (Gütiger, "de" maybe origined from french), "lok machas" (Ven. Lord, Sir) or "Lok ta" (Ven Grandfather), but the last is actually familary and better not, so one gets not attached as being owned.
In regard of adressing each other, Norum, Moritz, since you do not really know each other and aslo not the virte for now, both do good to adress one stage above the only age depending classification. So Norom is good adviced to call Moritz Boung (großer Bruder) , or Lok Boung (verehrter großer Bruder) and Morits would do best in calling Norum, Lok Srey (ehrw. Frau) oder Boung Srey (große Schwester)

Moritz, you are already more Khmer (khemā, land or person with virtue and at peace) as most Khmer would see and you yourself. Just be careful that you do not become just a normal nowaday Khmer, who is simply attached to a certain identification.
Its good to see this topic, and its good to have participator who actually recognice paying respect, enjoy it, support each other in making it perfect, beeing of respectful nature is one of the real treasures a person can own and very seldom in this world.

* Johann to Moritz offtopic: (As long as there is even the smallest chance, Atma does not give up, but one needs to know that Atma can not create such for others. Also a comfortable easy maintainable Zimmerpflanze, even a Kaktus dies. Its not sure if there will be any of this arround any more. Actually Atma, as it looks, is the only or the last Tudong monk as far as the messages and views reach. So what would be more worthy to give up and for whom? It always sounds very conceit colored and self lifting, but those are simply facts for now and anicca as all other sankharas. Norum and many other, actually do not know whom or what they meet and easy mix appearance with certain perceptions one has. You have never met and the chance is very, very small to meet such a ugly and disturbing person again as well such a gatering and place. What ever one maintains, unterhaltet, will survive for one. That is something very importand we should think of and here Atma comes back to the topic. )
In Cambodia its like in the late gone days of the Church. People will constantly pay respectand ask for forgiviness, on and on. Doing wrong, using Siladay like Christians go the Church... people think that the ways of the world, to make one happy by bowing down, so that one is beloved, counts also for the law of nature. Actually its creating much confusion and is not good karma, if one even knowingly respects of what is not wothy to respect.
The more one urges people to real generosity, Silas, concentration and real wisdom, the more people dislike it and prefer those who are tell: "Oh, don't worry, we are all like that. We are wordlings. Its normal to make wrong. " cheating people by telling them sweet things.
* Johann offtopic: gesprochen von Bart. Gestern dachte Atma, nun werden die Upasikas bald dem Moritz gemeinsam schnappen und ihm die Haare und den Bart stutzen
Khmer fürchten sich zumeist vor Leuten mit Bart und langen Haaren. Oder, wenn er sich weiß oder in Robe kleidet, verehren ihn als Brahmanischen Asketen.
Bach to topic, if Norum could share a bigger picture where also text is read able Atma would look through the text.
Since Namasakhar is something that needs to be made threefold, Atma would like to teach how to do. In Cambodia there are nearly no people who know and do it. Actually by doing it rightly, by body, speech and mind, one would be able to even reach the state of sotapanna which only this deed. Lets look if Atma can make even pictures or a movie to see the bodily part.
Its not taught anywhere and the usual is most a merely lazy following others.
