Never even occurred to us to offer financial help. We just always told our kids their bedroom was waiting for them if the need came up. Neither kid moved back in and both paid all their own bills. Well, my wife and I did give our daughter a burglar alarm system with cameras when she bought her house, that only cost $150 for the installation and $30 a month for the monitoring.
Always makes me sad when I see how low teacher salaries are in some parts of the U.S. Fortunately that isn't the case in the district we live in IMHO. They start teachers at $47,000 a year here.
