Living with Bob and "Al"

Sheri has been sorting through the boxes and boxes of paper clutter she brought with her from the house they lost. She found a stack of index cards that Bob used to use. He kept them in his pocket all the time. This one had a note to himself about Sheri and Bob's anniversary. She knows the card must be quite a few years old, because "Al" has not mentioned their anniversary in about 4 years now, and he can't spell anniversary anymore. Maybe clutter is not so bad after all.
