i have a very weak immune system...i get sick every 3-4 weeks....when i was picking out my first bag (the pochette) my mom said that I could ask my dad that if i went to school everyday from that day that i could(like if i just got a headache, or a stomachache), he would buy me a speedy at the end of the year...of course, i could not wait that long, so i got my pochette, Chester.....i love him!
