The context of the following conversation is Casey took her dog out for a walk to get it some exercise on a nice day.:
Casey says Can we push lunch for like 15 minutes? I need to shower..
The friend responds Oh yeah, no worries. I'll just let Marty know we'll be a little late..
Casey responds Cool, thanks. I took the dog out for a walk since it's so sunny but we stayed out longer than I expected..
The friend responds I feel so guilty taking them back in when they're so happy outside!.
Casey responds I know! I couldn't break his little heart like that..
The friend responds Marty will understand. He loves dogs too..
