Back when I was in college (the first time) I had a roommate who worked part time at a group home for adults with Down Syndrome. Many of the clients had lived in group homes or institutions for most of their lives, and as with any group housing situation, often the behaviors learned were not ideal. One of the things that many of the residents could do was projectile vomit on demand. (My roommate had a great story about a new employee who had barricaded herself in the kitchen with the doorway completely covered except for a six inch gap at the top, whereupon one of the residents kept jumping into the air and vomiting into the gap. Fun times, fun times.)
Anyhow, I bring this up because it occurs to me (yet again) that this may be the only way to keep some people from carrying on with long boring conversations around me. In a quid pro quo type way, if you yack near me I may yak on you.
This pertains especially to conversations about computer games, but endless details about bicycle races may also qualify. Using a conservative estimate, I have been forced to listen to at least three hours worth of conversation/monologues on the two subjects this week. I'd prefer to listen to someone scrape their fingernails down a chalkboard.
So, take heed. You have been warned.
