Interesting. I suppose it's possible, but I'm pretty sure he doesn't even have my home number. We talk from time to time, usually on our cell phones or texting, but never on my landline. The callers usually say
he gave them the number, but I mostly think that's BS since a) I'm pretty sure he doesn't have it and b) I once asked him if he'd given anyone my number and he said he didn't. And my brother is many things, including frequently kind of an ass, he's not typically a liar variety of ass. I suppose I shouldn't rule it out.
