Hi All
So I'm in my usual pickup spot today (Starbucks) and I see this amazingly hot blonde chick walk in. She went and sat alone to drink her coffee. Anyhoo, after she'd been sitting there, I decided I needed the loo, and since she was sat by the entrance to the toilets, I figured I might try a pickup. The setup was perfect. Approaching the toilets from where I was meant walking past her at a slight angle, so it wasn't too confrontational, and also I could pass off talking to her as if it was a last minute thought whilst on the way to the loo. It was the perfect setup. Anyhoo, I walk past her, and she looks up and smiles, I smile back then shit...
I couldn't think of an opener. I walked past and went to the loo, figuring I'd use the minute or two in there to think of an opener for on the way back, but I couldn't think of anything. It was like a total brain freeze. Normally my problem is Approach Anxiety, but I didn't have that this time. I really was up for picking her up, but I just couldn't think of a way to start things off.
This is the first time this has EVER happened to me. I'm a pretty gobby bloke and talking bullshit generally comes quite naturally to me

but I couldn't think of a thing to say.
Has this ever happened to anyone else before. How do you conquer it?
