New People, New Problems?

When we let someone into our life, we are lowering our walls, we are becoming more vulnerable by the second, to let them know we trust them but most of the times that is a really good idea.
Why is it that when we are trying our hardest to be nice, kind and friendly people assume that as being fragile and try to take advantage of it just to make fun of you. 
If you start talking to someone because you think they are funny or that they would be a good friend, they give you attention and seem interested in being your friend too but then you find out they were just being friendly cause they wanted to find stuff to make fun of you.
Once that happens it's almost impossible to trust anyone again!
That has happened to me a lot but now it doesn't bother me that much because I came to the conclusion that it's their lost not mine. I will always try to make new friends, some of them, sometimes not who you expected, will become your friend, while the other will spending their time mocking you, you just need to accept that some people love to hate so let them spend their time talking shit about you because the people who matter know the truth, so enjoying your life with your friends and never never NEVER stop being yourself!
Love life
