Second of all, what's a lovely first or second date dinner without some wine? If I turn down wine when he offers, that means he can't get a bottle either, and where are we then? Staring across a table each other, disappointment in the air!
And of course if you don't drink during the dating ritual, you inevitably get the question WHY you aren't drinking. And ladies, let me tell you, admitting you are dieting wins you NO points with guys. First off, it somehow implies that perhaps you are overweight (he thinks it even if his own eyes tell him you're not!). I'm sure you know this is not a thought you want in his head. And of course it somehow suggests you are high maintenance or vain (which you are of course, but that shouldn't be revealed just yet!).
So ladies of the world unite. Don't listen to those silly diet gurus when they say you can't drink! My guess is that all the people who create these diets are A) Married B) Very, very old. Thus they clearly don't understand the perils of being a single woman! And I'd rather be happily dating and imbibing than movie star skinny anyway!
