Why?

Our water heater pretty much exploded tonight (well, without the fire part...and actually it was just the expansion tank, but still...). I was about to get into the shower after a long day of yard work, but here I am hoping Paul made it to Lowes before they closed at 10. He left our house at 9:52. Just wanted to let you all know, I am kind of in a bad mood! Our church friends might be in for a stinky treat tomorrow (meaning me, and probably Paul too, without a shower).
