Why Couldn't I Have a Boyfriend?

At the place where I'm temping, the lawyer rents out space to other lawyers, which makes them sub-tenants. There are some former sub-tenants who still receive mail here, which means someone has to come by on a semi-regular basis to fetch said mail. One of the people who is a fetcher is a bald, corpulent man. He's probably in his late 30's or early 40's. He walks with a cane. I temped at this place last year, and I remember this guy from then. He'd come up the stairs, ask if he had any mail, and I'd hand it to him. After a while I got busy and told him he could just help himself to the folder where it's kept.
I started temping here again a few weeks ago, and the second day I was here, when he saw me he asked what my plans were for lunch. I was planning to run a bunch of errands I hadn't gotten done before starting to temp, and told him that. When I heard his response of, "Maybe some other time then?" I realized he'd been trying to ask me out. Oh.

Yes. So. The truth is, I had zero interest in going out with him. Even aside from not being physically attracted to him (and it's not because he's bald - there are plenty of hot, bald guys), there are other issues. I'm attracted to people who are smart. Nothing in our brief chats ever led me to believe he's smart. I'm attracted to people who are funny. To people who are the slightest bit extra nice. He did not seem to be any of these things. Plus, every day when I see this guy, he is wearing sweatpants. Not even just regular sweatpants, as if those aren't bad enough. No, he wears sweatpants with elastic around the ankles. Also, he tucks his t-shirts into the sweatpants. To say it's not a good look is a severe understatement. I never really liked the show Seinfeld, but sure did appreciate when Jerry spread the word that it's unacceptable to wear sweatpants in public.

Anyway. If you feel that I must be a snob for not liking this guy, and not wanting to go on a date with him, then so be it. You're attracted to whomever you're attracted to, and I'm not attracted to this guy on any level. I mentioned this asking-out to two people - my friend, and an associate who works here part-time. My friend told me, "Just tell him you have a boyfriend. You have to lie; it's the most humane thing to do." I agree with her. Any other reason I'd give for why I won't go to lunch will just translate to, "I don't like you." And even though I don't, he's not a bad person, just a bad dresser. No reason to make him feel badly.

The associate also told me to lie and tell him I have a boyfriend. But here's the reason it bothered me that she said that: she assumed I don't have one! My friend is my friend - she knows my life. The associate doesn't know I don't have a boyfriend! Why would she assume? Do I in some way LOOK unboyfriendable? I wanted to attack this point and force her to feel as badly as she'd (inadvertently) made me feel. I dug deep down, realized I felt nothing, and borrowed maturity from someone else in order to keep my mouth shut.

But it really hurt my feelings. And every time I think about it, it hurts my feelings all over again.
