Husband's dog does this to me all the time. She goes out the dog door, then crawls under/jumps over/teleports herself past the fence and comes to the front door and barks, barks, barks. If I hope the door, I swear she looks at me as says, "Ha ha! Look! I got out of the fence again! You can't keep me in! Fuck you!" because she won't come in, but she doesn't want to be shut out. I hate that dog.
Wait. You have the antibodies for the parasite. So doesn't that mean your body killed the parasites? I don't like to think of you having parasites. Parasites can't be good. I mean, they're PARASITES. Like lice. Or tapeworms. Or cooties.
Well, at least you had an umbrella. I wouldn't even had had an umbrella with me. In fact, I do not own an umbrella. Confession: I am afraid of umbrellas. Terrified, actually.
