On Saturday, I texted her a joke about her dog in which she replied, then she sent a second text asking what I did yesterday. I mentioned going out with friends then joked about her hurting her leg, etc.
I asked when she'd be next free so I could nurse her poorly knee. She replied "Don't know until tomorrow! When are you free" (hasn't got her work timetable yet) so I told her not Sunday or Monday because I'm working really late. She said "Ok I'll let you know!".
I haven't heard back all of Sunday about it, should I ask about it?
