Heres a good one for you. My son-in-law grabbed for a knife that was falling and cut his pinkie to the bone. Leave it to my daughter who use to be a vet tech but now a research scientist who works with ratS. She got out needle , suture and all the sterile things she needed and sewed it up. This is the kicker. T he suture was blue in color so while she is stitchinh him up, my 8 yr. old granddaughter says to her.Mom don't you know your suppose to use the same color thread that matches what your sewing. My granddaughter the seamstress ha!ha!
