One of our neighbors was in the local restaurant for lunch one day when a friend asked him, "George? What's your wife do every day when she takes your 4430 out?"

"I don't know that she does."

"Yeah, I see her 'bout ever day take yer tractor out and goes down the lane there to the west. I just figgered that you had some stock back there that needed fed or something but she never takes any feed or nuthin' with her."

So the next day, George said that he left home as usual but parked part-way down the road where he could follow her. "Heck, she's been meetin' the mailman back there along that empty stretch!"

I guess that'd be considered social interaction.  :-)
