When somebody gives you a free gift, I think it's pretty fair to accept it without questioning their reason behind giving you a gift. In fact, it's weirder to turn down a free game over an assumption.
I don't think it's right to accept a gift from a complete stranger. You don't know them and they might be creeping on you or something.
Doesn't work like that. It has nothing to do with how smart people are.
Why do you think girls ignore a lot of guys? Because they offer or show off nothing that would make the girls life better. Nothing that would help boost their offspring's life quality. Pretty sure it's a psychological instinct. Girls are looking for wealthy guys who can handle themselves and protect their family and maybe as a bonus be good looking. Wealth shows that you can take care of your families needs, food, clothes, ect. Protection comes within natural instinct but this is mainly strong alpha males with good body builds. People who aren't afraid to get blood over their white suits. And of course good looks to brag to others to make herself feel better and more confident that she didn't end up with a loser.
Some people I know don't like to flaunt or don't like people flaunting around them. I know we are all literally animals and our behaviors can be explained biologically, but I think for us it can also depend less or more with our personalities because I do have friends who likes when girls flaunt themselves. Heck, one of my best friends thinks one girl at my school is really hot and kind. Yes, she's hot but she is a slut, she curses like all the time and she hates me and some of my friends.
