A: This is one of those tricky situations where you just have to accept that people will complain -- but it's your home, and your family, so you get to make the rules. To make it go more smoothly, try saying something like this, "I know it sounds fussy, and I'm a little nutty about this, but would you mind washing your hands? There have been terrible flus and colds going around Lindsay's school and my job, and I just can't afford for everyone to get sick again. Sorry!" You might also have a little bottle of hand sanitizer available to make it easier.
