Pshaw, girl! You do plenty! We can take care of ourselves, and unless Humaworm is killing us, I'm sure we can all help each other.
Please don't feel like you need to take even MORE time away from your family for this! Those kids and your husband need you more than we do. You can never make up for time you didn't spend with your family, trust me, and nobody's tombstone ever said "I wish I had spent more time working".
