I'll tell you mine. She had been visiting with me, without ever leaving, for 5 consecutive months. I had the engagement ring. I bought something at the grocery store, don't remember what, and put the engagement ring in the ring box inside the grocery bag.
Now, DW is quite mouthy and bossy. So, I brought home the single grocery bag, ring inside, handed her the bag and said, "put these groceries away", and walked into the next room. She started cussin and mouthin and slammed the bag down on the kitchen counter talking about how she wasn't putting away any groceries. Then I heard silence and a little gasp, so I figured she had found the ring. I returned, went down on one knee, and proposed.
