What does XO mean?

My bike friends who read this will think I am referring to SRAM stuff....but I was really referring to when theh chickies sign off with a XO? Ever since I was in 6th grade and Dylan McGee (2 years my senior and I had a major little boy crush on her.) signed my year book with an XO I have wondered. Hugs and kisses right?

Listening to the Strokes (is this it?...it has been about 2 years since I listened to it and enjoyed it quite nicely after having got stuck on a little Alanis Morrissette...Yes I just admiteed that ). Took a break from my project tonight. Hope to return with new found excitement in the AM after todays wall in which I just edited over and over...
Pictures of my cat zoe.. That seemed so long ago as if it was a different life other than mine. Yes, many things i do miss.
