Why does this always happen?

So, Luke's shoes have been MIA since Christmas. We have looked every where for them. Under beds, in closets, at other peoples homes. No luck. We kept waiting to get him more because we just kept thinking that they would show up somewhere. Two days ago we finally decide that we had better go ahead and get him some new ones. So, today as I was cleaning up the living room, there they were just sitting on the floor by the front door. What????? The only thing I can figure is that they were in the little table with all the drawers. Luke pulled all of them out this morning. I didn't even think to look in there. Anyway, at least I know that if I ever cannot find anything all I need to do it buy a new one and it will show up. Maybe next time I should just leave the tags on. Will that work?
