It's that time of the week again, so here's my tip and remember, if you want to play too (or just read the great tips out there) visit Shannon.
I have a lost and found basket in my house. If anyone leaves anything and I can't mail it back or don't see them regularly I put it in the basket. When they come visit again I check the basket to see if there is something for them. I keep it in the front hall by the door.
