Instead of phones and computers (which we couldn't afford even if they were available), she just sent us outside. We were only expected to be back by supper. I realize you can't do that now.
My mom would throw us out of the house, tell us to not come back until suppertime, and to stay in "the yard". Since we lived smack dab in the middle of a 1200 acre property, that gave us plenty of room to roam.
