One of my biggest pet peeves are people (especially those I share a house with) who get a new glass each time they need a drink in a period of a day. Thanks to my mom, she purchased "Inchbugs" for the kids. They were so handy and helpful, the adults needed their own too. Mine doesn't get used an awful lot because I have the strange habit of using the same coffee cup, water bottle and wine glass over and over. I have my favorites and my household and guests know not to touch or use. I am a happy camper now that my family knows to have an Inchbug on every cup, except Remy's bottle.
