Running up on an estate sale, not intending at all to find it, walking in (it was quite slow at the time) and finding wonderful treasures that no one else cares about or wants, staking claim to what I love and bringing home the bounty.
It may not look like much but it's all so neat to me. My ten year old watched me at this sale and said something like "Wow, mom you went nuts in there!" But you know the deal, grab it quick or it'll be gone . . .
