Bag o' Socks

I bought some socks today. Nothing important about that, just a package of Hanes socks, because I need some more. I went to open the bag and noticed a zipper seal, like a storage baggie. Sure enough, at the top of the package, it says "Resealable!" Hmmm. Why in the hell would you need to reseal the bag of socks? Don't most normal people take the socks out, put them in their drawer, and throw the bag away?? Do some people actually put the socks back in the bag after weraing and washing them, so when you open their drawer there are little OCD baggies of clothes? WTF??
