Hi T You are so lovely! What are you waiting for! Its a great idea. Call him and do exactly what your friend suggests.
You just need a line for the 3 possible outcomes: 1. He says great - love to. (T is suitably excited and has a specific plan that she is asking him if he can join her in) 2. He umms and ahhs and isnt sure if he can fit it in (T is calm and tells him to call her if he can work out a way for it to fit in) 3. He says he cant, he's too busy (T expresses disappointment but manages to make B feel like he's missed out on seeing her, all said in a fun happy way!)
And yes if you get there and see him, you must step up the flirting. Just look into his eyes a little longer than normal, or more friendly / lingering physical contact. I'm sure you can do the cute, giggly thing too if necessary, flirting should be fun - dont be scared!
You can so do this T!
I cant read the magical chair thing - says I'm in the wrong country to view it?!?! Weird?!
