This may not be realistic, but I like to pretend that it is. I have been trying to come up with an explanation for why I've never received affection of any kind that doesn't involve me being a freak, and this is the best I could do.
I think that everything I perceive, or think I perceive, is actually some sort of computer program that I have been connected to. The problem with this program is that it has certain limitations. I can see other people touching and being close to one another, and I can hear about it, but it isn't equipped to actually supply me with those things. The solution here is to end my "life" immediately, but I'd probably do that anyway given a chance.
One way to test it would be to find a hooker and see what she'll charge for a hug, but that too is currently beyond my means.
