Or am I finding hearts? I definitely don't seek them out, but they surely seem to "pop" up when I least expect them to. I suspect this "tab" was on a large plastic bag of some sort; but I am just guessing. It was in my son's room, and when I started to vacuum the carpet, simply lying there in plain sight ready to be sucked up. Wow! (It probably should have been thrown out a long time ago!).
