Okay, so - a bit of background... are you sitting comfortably? Then I'll begin.
The other day, I go into the post office to buy a stamp for an envelope I'm going to post off in the near future. I buy said stamp, and then wander off to the post-box outside the post office to get rid of said envelope... only for the girl behind the counter to come dashing out after me because I'd forgotten to put the stamp on. She gets to me just as I'm letting go of the envelope, and then explains to me that it'll have to go without the stamp.
Next time I go into the post office, she remembers me. We have a brief little laugh and chat about the incident, where she offers to put the stamp on for me, just to make sure that it goes on.
Here's the thing, though: she's really cute and friendly, but my understanding of mating rituals is poor at best, I can't be sure whether this was simple customer service, or a sign that I should have taken the opportunity to ask for her name/phone number/favourite sexual position (well, maybe not the last one, but still...). I'd like to summon up the guts to ask her out, but I need a real reason to go into the post office (rather than just going in there and blurting it out right off the bat, which never works well).
Point is, should I even bother? I've already been feeling the urge to attempt to get to know her better being replaced by my usual desire to pull on a cowl and cape and brood on a rain-soaked rooftop, which is never a good sign. I know that "nothing ventured, nothing gained", but still... akg, I hate this whole dating malarkey. Why can't it just be "tick this box here if you like me"?

I have been getting that sort of thing every now and again in my life where someone would seem to go a bit out of her way to help me like how you described and I still don't know what that is all about. It is funny you should mention the "tick this box here if you like me" thing. I once tried that when I was in the second grade, I had a box for yes and no, she scribbled in a third box and checked it. It said
. I haven't been able to understand women ever since.
