argh so bored

When Im not at work and my son is either at school or with his mother and after exercising and taking care of adult shit like household crap and so on, I get so incredibly bored.
I need a new hobby or something. I make my own mead and that is great but after the process of making it, you gotta wait at least 6 months to actually drink it.
Getting back into carpentry could be cool though but I am lazy.

what do you guys do in your free time after getting everything else done?
