I'm a bit like this as well. I don't worry too much if I am just late home, but more and more I find myself not wanting to be away for two weeks holiday. We always have someone come in and feed the girls when we are away, so I know that they are in their usual surroundings and they all have each other's company, so that aspect is OK. But I just miss them SO MUCH, and it gets worse the longer the holiday goes on. I now think that a week's holiday is enough; soon it will be a long weekend; I could end up a hermit yet!
