Can I “High Five” my duplicates from the Mirror Image spell?

The text for Mirror Image says:

the duplicates move with you and mimic your actions […] If an attack hits a duplicate, the duplicate is destroyed.

Does this mean that my warlock can cast Mirror Image, slay an opponent in the first two rounds, then spend the remaining eight rounds giving himself one high five after another? Then wave goodbye to the three images when the spell duration expires normally?

Or does one high five from the caster destroy his own duplicate? One destroyed image with each flat palm slap?

Assume that at the end of round two, no opponent has hit a duplicate, and the three original duplicates are still present when celebratory hand gestures commence.
