Resealable Bags

Is anyone else as confused about resealable bags as I am?

The other day I saw a package of socks. A resealable package of socks. I really couldn't figure it out. Why would you want to reseal a package of socks? I have no clue.

Tonight, I opened an economy size bag of frozen burritos. (I foresee more comments regarding that than my intended agenda. And I suppose that's rightly so.) I looked for a tear strip. There was none. I looked for a pre-cut slit. Nuh-uh. I ended up cutting the bag open. Then when I put it away, I folded the plastic over and wedged it in the door.

What is this world coming to?

Why would I be able to reseal socks, which go in a sock drawer, and not food, which goes into a harsher environment than most socks ever face??

Seriously.
