Loving reminder: that store clerk, that cashier, that gas station attendant working today -- they have families, too. So, maybe you're stressed about something you forgot for the big dinner or some family squabble, but don't take it out on them. Be kind. Be considerate.
@charlotteclymer In Belgium, when they work on Dec 24th, I always tell them "thank you for working today". They are always surprised to hear it, but so happy. It's good so see a smile on someone's face, all it needs is a "thank you".
