Handholding is the best kind of PDA. Kids kiss during games of truth or dare and spin the bottle. Teenagers make it to second base with a little bit of liquid courage. Adults sleep together just to satisfy a quick itch. All can be done with zero emotions behind them. But handholding is such a sign of intimacy and belonging, at least to me. I’m not going to interlock fingers with just anybody, especially not in public. You’ve got to be very close to my heart.
