David lifted his head when he saw the girls come over to him. He scooted over a bit so he was sitting closer next to Erin. A hand accidentally placed on her side. Once they saw that, they backed off rather quickly and left. He watched them walk off, then looked at his hand, quickly taking it back and signing, "Sorry" about five times to her. He didn't mean to do that, but he was relieved when the girls left. He was a shy and sweet guy nonetheless. "You can come over whenever you want. I don't mind it" he signed to her with a shy and 'i'm sorry' look on his face. Hopefully, he didn't do anything to upset her. It was an accident, and he didn't mean to place his hand there where it shouldn't be. He didn't even know if she had a boyfriend, so he was being extra cautious.
