I'm going on a long weekend with friends leaving my wife with the kids at home.
Won't you miss your wife and kids?
I've got better things to do by having fun with my friends when my wife is away.
Having a weekend getaway with friends is understandable as long as your wife doesn't mind. But, your friends should never replace your children and wife.
I love my wife and kids, I'm doing this as gift for all of them.
I hope you have fun and by the time you get back you will be happy to see your wife and kids.
