Ahhhh. I give it six months, and you'll be back in there at least part time.
Two situations: #1-You'll get bored, and need something to kill time. Spare time is so much more rewarding when you don't have as much of it.
#2-Your (old)shop will get so busy that your boss will be *begging* you to come for at least a few days a week to help out, and you won't be able to say no.
I've seen it before, it will happen!
