This is turning out to be quite the thread.

On the subject of fix-ups, whenever my family is together, my mom will ask my brother if he doesn't know anyone he'd like to introduce me to. The topic makes me want to either laugh hysterically or go searching for our birth certificates to ensure that we actually have the same parents. The friends of my brother who I've met over the years are either so bizarre and out there or just plain creepy that I have to give him some props for not ever trying to set me up. Sadly, if my brother wasn't my brother, I don't think I'd know him in life. We're that different. In contrast, I know someone who met her husband because he used to be her brother's roommate.
