A hole in my sock

Today I have a hole in the bottom of my pantyhose sock. I'm not sure how it got there, probably through wearing it. I noticed it while I was on my way out.

I didn't bother to change my sock, simply because it's still useful. I can't go about throwing everything way just because it has a small flaw can I? But then again, I can't keep everything either.

I think I shall wear this sock still until I cannot wear it any longer. That way I know it's done it's full service, and that I didn't just toss it away to the pile of refuse too soon.
