If I was going to list the benefits of modern life (including all this internet stuff) I'd say that online supermarket shopping is way up there in the top ten. If your stepdaughter wants you to get out of the house more, then at least go out and do something you enjoy and not having to lug around a week's worth of bread and milk.
I'm sure she means well, though.
For myself, I tend to panic if something is sprung upon me... I need to count to ten (or maybe a million) and work out the implications of the problem... usually before I decide to stick to the same old same old.
