a stranger does something nice for you (and not in a creepy way either).
We have a little shop next to our office building that sells drinks, chocolate, magazines etc, and I pop in most days to buy gum or a drink or a little thing like that.
I am always polite and friendly to people who work in shops like that as I think it must be as boring a heck to be stuck in there all day! But the man that works in this particular shop is always really grumpy with my work mates....but not with me....and today he gave me a ktikat for free. Its just a little thing, but was a nice thing to do, and it made me smile. The girls in the office think its because I am pregnant that I am his 'favourite'....still I think its just because I am nice to him.
Anyhow - I hope that someone does something nice for you today.
