Is it normal that i don't find greeting or thanking people natural?
So, most of the time I don't find waving or greeting someone natural, nor do I find saying "thanks" or "please" natural either. I of course do both these things regularly because I'm supposed to, but I'll often enter a room with people and won't say "hi" to anybody, or instead of waving or saying "hello" to anybody to catch their attention, I'll probably just nod my head or do something else to catch their attention.
Again, this is all stuff I don't find natural, it's not that I tend to not do it because I don't want to or because I have bad manners, it's just won't cross my mind when I'm supposed to do it.
