If not, then just let her be for a good hour before asking her if she's OK. Initiate a brief, strong hug but be the one to break it. Maybe a nice, just slightly lingering kiss on her forehead.
Everyday kindnesses are good too. I used to cover my wife up with the blanket when she fell asleep on the couch, or pull her car into the garage. Not too much of that stuff -- maybe 3-4x/week.
