Short answer, a lot. Might sound as bragging, but it is the truth.
However, there are also a lot of things that I am not good at. I'm not perfect, but who is?
But if you want to know some of the things I'm good at, it is;
Massaging (Magic Fingers...)
Connecting to people (What can I say...people like me)
Because I like almost everything, I am boring in that way, but I cannot limit myself to listing only a select few things.
My computer - With it I can explore more of our society and our world. Also it lets me have fun with myself via gaming and such...
My brother - Does he even count as a thing? Nevermind, I cannot imagine a life without him. Sure I don't always talk with him or meet him, but knowing he is there for me if anything happens is important to me.
Sex - Sex is great. A life without sex...well that is a life I wouldn't want to live.
But don't take it as I'm a maniac about it, I'm just honest about it.
