I know this super hot girl that is unavailable until Wednesday of this week due to relatives visiting. She told me this a week ago.

I am going to this event that I know she would have died to go to.

Is it worth saying something like "It's too bad you're busy. This [event] is awesome"

Or something like "I'm going to [X]. You should come." and then having her remind me, (but probably hate) that she can't go.

Or do I just text after the fact and say 'Wow, went to [event]. Its too bad we didn't go'

How can I maximize this!? And thanks!
