Sandra made a face at him, Is he serious? she wondered.
Sandra made a confused face and fidgeted with a piece of lint she'd found in her pocket. I think he was trying to make a joke... I think. "Umm, yeah that probably would warm me up, heh heh." She forced a laugh and then suggested, "Lets do something fun." She needed the awkward conversation to end, now.
He looked so hopeful and Sandra didn't want to break his heart, but she smiled and said, "Yeah sure, Ian, as friends."
His face went blank for a couple seconds and then he nodded with understanding. His cheeks went scarlet and he muttered something about having to get home also.
