Yesterday, one of my co-workers was showing us this catalog (online version). It contained products for students - mostly, I think it was to address their physical fidgets and keep them mentally focused. For me, I think if I had do pick one this would be the front runner.
Make your plans now! Tomorrow is Spinach Day. Sadly, I don't think we are celebrating. My husband and I actually really like spinach, but we are planning to take the kids out to dinner. I don't foresee ordering spinach, but we will see. I could be tempted by a nice spinach salad.
