It all depends. when I was married, my ex did not want to do anything during the week, it really aggrevated his mother who complained that when his father was alive, he would do things all week.
It really bothered me because when the weekend came, all he wanted to do was "rest" did I mention he was only working part time?
For me it all depends, there are days when I feel it's imperative that I mow the lawn. I do my best to save the major, major tasks, like heavy digging, for the weekend.
Vannie, I totally agree with you on the Friday after work shopping - definitely a no for me too. I actually prefer to get up at the crack of dawn on Saturday and head to the grocery store.
