- When you're having a great time at Thanksgiving with the extended family... and STILL in the back of your head, you're calculating how many hours until you're back home and can check the forum for updates (because your parents are far too attentive to their computer's browser history).
- When you recycle forum bon mots in Thanksgiving conversation as "this... uh... friend of mine mentioned something about the Norwegian Army (or Spanish idioms, or anime soundtracks, or the Tasmanian apple industry)" because you don't want to explain the concept of "hanging out on a forum" to elderly relatives.
