A while back a QB member posted an amusing background on the southern term "Bless your heart". Something about the context it is used in can be a very classy way of saying "stuff it" (or even worse expletives if that is what you think!). If they do show up and start pointing out the so called "right" way to do things, just say "well bless your heart for saying something" while thinking bless your heart translates to "go %*$& yourself" then quickly add, I would love to see what you mean can you show me where your donation quilts are so I can go look when I get a break from volunteering? Of course this all depends on how they offer their advice. If you perceive it as well meaning, genuine, and offered as a way to improve your skills then bless your heart will take on a literal meaning. Don't be on the offensive should the occasional pearl of wisdom come along.
