#4 Saves money. Parking in Toronto is pricey. Plus, those gas prices aren't pretty.
#3 Time to finish that last-minute report or prep for that meeting I had forgotten about.
#2 How else could I sleep through the commute and get to work on time?

Details: Memories Sock Yarn from KnitPicks, 2 skeins. There's probably enough left for a third little sock, but not a fourth. I'll use it if I lose one of the above. My socks: 64sts around on 2.5mm needles, DD's socks are 42sts around on 2.5mms.
