We've been empty nesters off and on since 1994 when youngest left for college. As long as we are alive our home is their home and they are welcomed back at any time. Daughter moved back for 3 months before her wedding because her lease was up and son moved back for a year after grad school. Sorry, I cannot imagine charging my children rent.
lol TanyaL..we were Holiday Inn South for all sorts of kiddo friends coming and going during the college years. Loved it.
DH and I enjoy being "on our own" again. You just have to enjoy life whatever stage you are at in the scheme of things.
