Sorry about the flowers. I am sure your H will be even more jealous tomorrow!
Regardless, I think it is a great idea to get out of the house, no matter taking a course or working in a store. Can you take a night course in a local college? A class would only take one night a week plus a few hours of studying time like the one I am taking right now. It sure will be a much better investment to your human capital than a paying grocery post in the long run! Plus it is a good place to meet lots of young, motivated and unmarried guys are in a college too!
