I like this, but not things I wrote instead of using existing lib took weeks, not an afternoon. And I didn't think they would take an afternoon. If it's trivial, probably use existing lib. I don't know what my rule for deciding this is....I don't think I have one. I just make decisions. If I don't like a library I won't use it.
