[glances] when you least expect it

It's never expected.

Perhaps she mistakenly got the idea that you'd glanced more than once and perhaps you had but you couldn't let on to yourself that you had. So she drops the head and retreats behind her eyes to sneak a peek and you become aware she's actually staring in a non-staring way.

You try to drain your cheeks of any blood which might have inadvertently found its way over there and start the checklist - tummy, muscles, hope the face is all right - oh it's too ridiculous for words and then you stub the toe on the chair as you go to sit down.

She's convulsed with silent mirth and you sigh to yourself. Time comes to part and she goes her way but doesn't go far, organizing her jacket, hair and so on. You walk out there, matter-of-factly and ask if anyone in the general area can change a fifty.

She can't so you make a dry remark and it comes across as a witticism but you only realize this once it's all over.

Nonchalant spring in the step

Now there're absolutely no more constructed situations either can devise so it's a matter-of-fact farewell and you curse as she walks away and you skip across the road through three lanes of traffic and give a quick glance back over there, just as she also does.

With a newly found spring in the step, you'd whistle if you could but you can't so you don't.

So you go home and inflict it on your readership.
