Think about the people who is closest to you, may it be family or friends. Now think about all the good times you've had with them; all the times you've talked about someone to them and ranted and laughed and gone on walks and all the gold stuff about them.
No think about whether they do that with someone else. Think about how close they actually are to you. Are they really as close as you thought? What about if they went to someone else and talked about you. Or they talk about the stuff you like and laugh. How does that make you feel?
It's like we all have no one. Just you. On your own, facing the world and all its cruelty. That's a horrible feeling, so don't do something just because someone else is. Do it for yourself because if you don't you will end up regretting it.
