It fired off a swap

That hug had fired off the remote, but as Rebecca was not touching it, only you were aware of the swap. You noticed the first beam had hit Rebecca, and wondered where the second beam went. You watched as her entire outfit changed mid hug. Rebecca was now wearing a long dress. It reached almost all the way down to the floor, and right up to her neck. You instantly recognised that this dress once belonged to Mia G. She always dressed in dresses and dressed conservatively, now Rebecca did so.

You bade your farewells and you went to your room, passing Mia G as you did. It was weird seeing her in Rebecca’s outfit and not a long dress.

Thankfully, noone seemed to notice.
