Two thieves crucified with Jesus - they both began with taunting, but one underwent conversion. The thought had never occurred to me before though - why would anyone hanging on a tree muster the strength to mock someone else? And the only answer that came back was my answer for why I watch (and almost always mock) reality television - in my heart of hearts, my comments make me feel superior/clever/funny and, if only for a couple of moments, give me an escape from my problems (cross). It's all a sham of course: if I were on television, with people observing my daily foibles - I would provide them with a motherload of mistakes.
There has to be a better way to deal with our crosses, and I think that second thief, called Dismas in tradition, shows us how- acknowledge where we are and then ask Jesus to keep us in His memory (His Heart). Handling it that way is redemptive; just ask Saint Dismas.
