I see a lot of "whatever we decide" sort of responses in this block. OK, thats obvious. Take a chance and write something, won't you?
Depends on weather, we can't enjoy the great outdoors in a thunderstorm. A walk through a mall/dinner would be fine if weather is crummy, find a nice neutral place to talk, coffee is always a good stop though a bit cliché. If its nice out, there are other possibilities. A bike or skate trip would be nice, with a packed lunch ... maybe some kite flying, I have enough kites to share.
