This week I completely take my hat off to single parents, especially those with more than one kid. It certainly isn't easy juggling parenting, work and general day to day stuff when there is only one of you.
My wife's been away for the last 3 days and I've discovered this first hand - it's certainly doable, but you end up with no...zero....zilch time to yourself and this can't be good for your state of mind. I only have to sustain it for 3 days, I would certainly go mad doing it all the time.
So, to single parents that manage to do this all the time.... you rock!
