I found tubes of caulk until the day I left the house for the last time.
After I was redirected to the NPD thread and was warned about the caulk, I kept finding it everywhere. In the storage room, in the barn, outside the been, storage shed, kitchen, utility closet bathroom. I kept 6 unused tubes on the fridge that I had found, so that every time I saw them it reminded me what was and made me smile and laugh.
Funny thing, he was lousy at using it.
So, when dating a new guy, check for many tubes of caulk at his house.
