Hold her hand

A few years back I heard an older man talking about what makes for a successful marriage. He was counseling a young guy about what habits to start early in marriage. Frankly, I only remember one of them:

"Hold her hand when you pray together."

I've become consistent on this one, guys, and it really helps. Just don't squeeze too hard :-) And be prepared to be happy when you get a few 2nd-looks from strangers.
