store a box labeled "DH's Mom", where I can store all the crappy things she's ever given me that I've felt the urge to throw away but haven't in case she ever comes so she could see that I kept it and like it, and I can actually find them when, say, she comes to visit. Like she is tomorrow.
Except I can't find them. Well, not that I've tried, I am here, aren't I, while I hear DH diligently scrubbing bathrooms and vacuuming.
