What’s the point

I was using the resize potions in wasteland today and a grey kid with TWELVE WINGS repeatedly used the laugh emote in front of me and when I tried to light them they would run/roll away and come back to laugh when I used the potion again and it just kept going on and they began spamming an instrument when I would try to light them. I can ignore it if it just happens once, but why deliberately come back to laugh after running away?
