How to spike a guy in ten days

It seems I am not capable of correctly answering the question So, what do you do for fun?. Every time someone asks me that I scramble for an answer, realizing that what they would consider fun is not what I would consider fun, so I either have to lie and make something up or say I like to read, watch movies, buy clothes and write literary reviews and watch the blank look on their face when they look at me, prompting them to again ask, So, what do you do for fun?. Of course, I also run the risk of looking pathetic if I take too long to answer the question - because that implies that if you can't answer the question, you don't know how to have fun. Or I could just say I kill kittens and exploit little boys, and maybe that would satisfy them.

I just met a guy today (who I may have to call Cryptococcus Guy, because he's one of the dudes responsible for trying to control the pigeon problem in my building) when he came into my apartment to put nasty-looking spikes up on the roof overlooking my balcony, supposedly so pigeons will not hang out there as much and shit on my deck. We chatted for a bit and in a rare moment of weakness, I actually gave him my phone number. Now I am trying to decide if I should go out with him should he decide to call, or whether I should screen his calls and pretend it never happened. Unfortunately, he does know where I live, and he could easily track me down. I suppose he couldn't be any worse than the asshole from January, and he doesn't look like any past boyfriends, or have the same name, but I did get a similar response from him that I have gotten from others when I tell them what I do (and that it required 6 years of university): Oh, you're smart. I don't think I know how to answer that question either: Yes, thanks, I am, or No, you're just dumb, that's all, or the standard fall-back Oh, I went to school for a long time but didn't really learn anything. I don't really want to go out with some pretentious university professor, but I also don't really want to date a construction worker, so what's a girl to do? There don't seem to be many rugged yet quietly intellectual guys in my mid-sized Canadian city. These are confusing times we are living in, are they not?
