The context of the following conversation is Skylar held her hand to Sasha's chest because she wanted her to know that she was serious about the promise.:
Skylar says Right, so you know when people make pinkie promises?.
The friend responds I think so, yeah..
Skylar responds I've got my own version of that, just to be sure I place my hand in someone's chest to let them know I'm not going to betray them..
The friend responds Ok that's weird but if it makes you feel better, I can't fault you..
Skylar responds It's a serious promise pact, I did it with Sasha earlier today..
The friend responds Hope she wasn't freaked out..
