I must suck at flat-fixing.

Many moons ago, I had a flat. I patched it. It held air. Life was
good.

I went away for a couple of weeks, during which my bicycle
languished on its hook. now that I come back to it--the tire is
flat. No problem, I'll just pump it up--and then I hear the sharp
hiss.

Do patched tires *always* continue to leak? or is my patching bad?

I'll just slap a new tube on it this afternoon and re-teach myself
how to patch. ugh.
