To clarify, by "creepy" I mean a couple of things: 1) not realizing the "personal space" thing or that I can tell that they're not looking at my face or the code on my laptop, but areas in between, and 2) not realizing that making a lot of sexual jokes (in general, not about me, or I'd have done something serious about it) and mentioning things like "if they run out of hard drive space, deleting their porn will be a last resort" do say things about their character and creep me out. Neither sort of behavior started until I tried to befriend them earlier in the year (not within earshot for the second one, anyway)...
At first when it was just the space/turning up often issues I did think of Asperger's, but wasn't too sure because some of my friends have it in varying degrees and are generally pretty good with personal space and such. Then the other issues started.
I have a new patron saint for you! St. Dominic Savio! He only lived to be 17 years old, but he spent his whole life admonishing sinners and being humble. Some reports say that he was popular with the other boys at school. Some reports...not so much.
"But," objected one boy, "it was only a joke."
"A fine joke you'll think it when you're burning in Hell!"
I couldn't have said it better myself. I might have said something like, "You won't be laughing when you're burning in Hell." I've said that many times, over the years.
"I didn't see any such great harm in them," protested another.
"So much the worse. Not to see any harm in those horrors, argues that your eyes are used to such sights and such an avowal makes your sin greater. Do you not know that the holy patriarch Job, though old and infirm, declared that he had made a contract with his eyes, that they should never rest on anything but that which was chaste and holy?"
Good old Job. He didn't have an easy time of it.
Too bad you can't get them interested in St. Aloysius, another youthful saint. He wouldn't look at girls at all, even when they were standing right in front of him. He definitely would have kept his eyes on his own laptop.
