(in reply to the original question): ie how much of an introvert or extrovert are you?
According to a number of Myers-Briggs Type Indicator tests, I'm extremely introverted. (Aye - me!) I'd classify myself as number 3. I do like other people a lot, but I get exhausted if I spend too much time with them. I need silence occasionally (hence escapes to the hills, etc.)

Normally I'm polite and smiley to absolutely everyone, it was just the way I was brought up to be. However, yesterday, I was a right grumpy sod, waiting in a huge queue to pay for petrol. The cashier was a youngish wee boy, who was slow as a slow thing - in action, speech and thought. So I was sharper and brusquer than usual (example, barking my pleases and thank-yous as quickly as I could, with no big smiles). But the cashier got his own back in such a classy way - as I stomped off, he took the extra time to wish me a safe and pleasant journey before he served the next grumpy sod in the queue.
Boy, was I chastened! I do declare I flushed a guilty red as I turned back to thank him with a furtive grin. Doh! Serves me right.
