Gettin' old, Mom?

One of the first signs of old age is surely when you save Kleenex in your bra or the saving of anything used, in general. While working with my Mom last week, I found out she saves the paper towels that we use to clean the dry erase boards. I found three of them, dried up with a tint of blue on them. So, at the end of the day after I cleaned the monitors in the testing room, I asked her if I should save the two pieces I used, considering they weren't really dirty, just wet from the Windex. Do you know she gave me a look like I was the crazy one? Why is it okay for her to save them and not me? I guess I'm just not old enough yet. Checked your bra lately, Mom?
