Shame on you Gayle!! Now they will attempt to calibrate eyes and we
are in trouble 'cause they will have to decide with or without
glasses and/or contacts, not to mention the colour charts to be sure
we know which shade of blue or purple or red is correct. Oh this is
frightening!!
Let's not tell ATF about recycling either.
Gaining that second year to get older does scare me a little.
