Why am I friendless?

This isn't one of those sob stories because I'm not sad or unhappy just curious.Why can't I keep friends for long? I'm funny, and I'm a great listener. I'm cute, I like to read, I love nature..I love to hang out, and have a good time, I am very goofy, and do random and goofy things. I can admit that I have a mean streak but thats only when people piss me off. I love animals, and love all types of music, I'm judgemental but I always give people a chance. I'll try anything once. I admit sometimes I can be reserved and quiet, but thats because I like to think before I speak sometimes, and I have to decide if I want to trust you or not. I"m a good person so why am I so friendless? Why can't people love me for me? Even my own family doesn't care that much about me except my mom, and sis, and bro. Am I a horrible person and by the way I'm 16. I don't think I'm a horrible person. I'm understanding and caring like what the hell..lol. Sometimes I can be impatient and speak the truth.
