Hey Jesyka, it really can be tiring being worried about how the other person will react. I don't know you or him, but one thing about what you said you said to him is there is a difference between giving feedback and giving an instruction (which some people don't take well).

Its perfectly fine to say "that's a strong aftershave. Did you use a lot?" But telling him to use less is ordering him to do something. For me I am fine if someone asks me to do something ("could you use less?"), but as an adult it can be demeaning to be told what to do ("please use less next time"). He isn't a child even if you might think he acts like one sometimes.

I am not saying this to criticize you, I am just trying to explain why he might react as he did.
