DON'T SAY "MHM" IF I SAY "TY" OR "GJ"

Where are your manners people?!? If you gank me succesfully and I say gj, don't say "Mhm", say u2 or something! I'M COMPLIMENTING YOU, why are you being egotistical? It's like I just gave you an apple and you somehow turned it into a lemon (and didn't make lemonade) like wtf? It's like getting rejected by your crush but you didn't even like them before you asked them out so now you hate them twice as much. Does getting along with people somehow repel you?
And when the jungler gives me blue, I say "ty", and then he says "mhm". You do realise that you OFFERED it me meaning you didn't want it, so why can't you just be a little charasmatic?
Even when I'm jungling I can't hide from people like this. I thank them for a leash and after I thank them, the first thing they say in the game is "mhm". Nice first impression, making yourself look like a self-entitled prick.
Remember how your parents taught you manners when you were little? WHY DO YOU NEED TO BE TAUGHT AGAIN?
