After all I finished with my bet headed home and was asking myself what could the colleague act that way avoiding his close friends they all gambling together and just because luck shines on him first he decides to create a distance and class. I couldn't actually annex a good reason why anyone should do that.
When I see stuff like this, it irritates me. Why do you have to change after winning money? Actually things like this happen frequently but it doesn't make sense. But use money to test people's behavior if you want to learn more about them. It Simply demonstrates that the guy is not a true friend. Why will you stop hanging out with your friend's now that you are wealthier than them? Perhaps he thing his friends will put all their financial problems on him, but if he is careless and ends up spending the money carelessly, he will return to the friend's he avoiding when he was wealthy. Allow someone to be wealthy if you truly want to get a sense of their true character. Not everyone you call a friend is actually a friend, some are simply acting like one because they are getting something out of you, but once they have money, you'll be able to see what they're really like.
