I work as a software tester.
Once I tried to explain what I do to my parents. They couldn't get it, not really. But it is ok since I get to throw countless issue founds to developers and watch them anxiously deal with them. Definition of fun.
I am a hobbyist developer myself. It is fun and creative, thus I enjoy it.
I also enjoy working out and playing basketball. And drinking coffee. Tons and tons of coffee.
