We all have our little quirks and habits; things we do without really thinking, routines we slip into every day. When you first log in, do you run to the mailbox even though you haven't any auctions up? Do you routinely jump on the Stormwind fountain or jump about the Undercity bank? Always repair at the same out-of-the-way vendor? Dance in bear form and wait for the tells to pile up?
It's the little habits that make WoW special, so -- what are yours? (All of the above are mine!)
Update: Sorry about the comments issue. Fixed-- comment away!
