One time my wife had to go to a party and she had to go shopping at three
stories in about 45 minutes. I told her, "Look, this time, let's go
'guy shopping'. You tell me the store and what you want, we'll
go in and buy it and then we'll go to the next store and do the same."
So she agreed. We got the shopping done and we were back home in time so she
could go to the party.That is synergy.
