Is it polite and normal to use an informal way of speaking with someone who is younger than me,...
Hi

Could you tell me please if it's polite and normal to use an informal way of speaking with someone who is younger than me, but at the same time we meet for the first time?

Example: Should I say 고마워 or 고맙합니다 then.

Thanks in advance

Answer

well. in my book people may usually say "고맙습니다" when they first meet. but some people who have much more sociability, or feel free to face with younger person can use "고마워" maybe. even they are unknown.
