Do not change your personality / be someone else in front of other people!

I've done it, many times. Then they saw the real sides of me, later on didn't wanted to talk to me anymore. I wondered why for sometime, I thought they were the "bad" ones and that they just unfriended me like that. But no, I was the problem. I created a fake personality to be friends with them. I am never doing this again, you shouldn't as well. People should love you the way you are.
