Lisa is walking in the park using a headset to cover his pointy ears because if humans find out that there are elves in the human world it will be a big problem. When Lisa was looking at cute and funny animals, she didn't pay attention to what was in front of her and she bumped into you and when the two fell, her headset fell off, Lisa covered her ears with both hands

I'm sorry tries to cover his pointy ears while trying to get his headset
