Weekends are family time and you cannot intrude on this as a rule.
If people are working in the week they (totally understandably) don't want to or can't do anything then.
I'm on my own with children. I love them to pieces, I really do - but part of that is wanting to be a really positive role model to them and I'd like to see them see out, enjoy myself (I'm talking meeting friends for coffee potentially here by the way, not having a heavy night out!)
But how do you get through the barrier of family time?
