To Monsumo, the laws of averages states that, all things being equal, you will get 1 in ten people interested. All things are not, however, equal, and some people have the intellectual capacity of a boiled potato (look around the forum, if you want to know who I am talking about). But to the OP, yes, go for it. If she turns you down, just remember that there are plenty more fish in the sea, and to get back on the horse, and that people REALLY hate cliches.
But seriously, just think that, as the law of averages states that at least 1 in 10 will be interested, at least 1 in 10 will not (the others will probably be swayed by your method).
