@sozobe,
(As a follically-challenged adult, I will ignore the 'bald' metaphor
)
This is an interesting tangent (I still hope James ignores this and just asks since I don't think this is relevant to his situation.)
This is a bit of a pet peeve of mine. What is wrong with honesty and directness?
If you don't want to go out with me, why the heck can't you just say so? It would save time and energy to avoid this silly awkward dance. It is annoying to have to play this little guessing game-- and it ends up being far more awkward then it has to be.
I would be upset with the let's go with Julia trick.
First, the question is "would you like to go on a date with me?", if I have the decency to ask a straightforward question, I deserve a straightforward answer.
But second, look what the response does to me. First, it is almost certainly a lie (or a damn convenient coincidence that you happened to be talking to Julia about this very restaurant). Second, it puts me in a difficult situation-- there is nothing wrong with me asking you out on a date (that is, when we were both single), I probably have no interest in spending time with Julia meaning that now I have to be honest when you wouldn't be.
When I was single, I appreciated a direct firm "no". I found that women would most often go on a first date... I appreciated the honesty on the second date... and a simple "I am really not interested" may have smarted a second... it was someone I thought I had a good time with not returning my calls, or making excuses that was really annoying-- I had to guess whether the excuses were real (not really that difficult, but a straight answer is much nicer).
