Hahaha! Wow! People can be soooo generalistic! Just because I saw a few french men with untied shoe laces doesnt mean All Frenchmen Don't Tie their Laces. And just because I chatted to an american who was rather dim doesnt mean all americans are stupid. A persons actions dont determine their race, and their race doesnt determine their actions. I have a friend that hardly ever says goodbye to anyone he chats to online (and he's not Polish by the way). I hardly say goodbye either because I usually always leave in a rush. Online Chats are very impersonal anyways, its very different to a one-on-one discussion over the phone or in person. I dont beleive you can compare the two.
This is VERY common. Remember, they are not really interested in what you are saying half the time, especially the women I've found. I thought it was only me. Another classic demonstration of their manners.
It's like an impulsive verbal diarrhoea session for them.
Anyway, I will say goodbye to all as it's almost 1am. Goodnight y'all :)
