The Brother Store...

I was at Costco with Nathan and he saw a gentleman there with 4 boys, a 6 year old, a soon to be 4 year old and twin 2 year olds.  He commented on the number of brothers that they had.  I said, "Yes, they have one more brother than you do."  He then proceeded to tell me he wanted another brother.  I tried to explain that he wouldn't be having any more brothers.  His response was that we could go to the brother store and buy one.  I told him that there wasn't a store to buy brothers.  He insisted that there was.  He was going to run there and use his allowance to buy a new brother.  If only it were that simple!
