The 'be nice to strangers' is something I did not consciously do until a few years ago.

It can be fun. You surprise them for one thing, you can see appreciaion and it makes shopping easier! Lol

It started with a story I read about random acts of kindness. I really feel this is a good way to make daily errands much more pleasant. We all have to interact, may as well make it enjoyable.

These are all valuable reminders. Just too bad we have to be reminded.
