Think About It
Be honest. The last time you said, "Have a nice day," to someone, it came out of your mouth automatically and unthinkingly, didn't it?
And the last several times you heard a cashier say it to you, you're pretty sure they did it the same way, right?
It's time we all stopped saying this so flippantly. Today is the day to Tell Someone to Have a Nice Day and Mean It (Day).
Make today the first time you've meant that sentence in a long time. Make today the starting line for when you decided to mean it forever going forward. Make today the start of something big.
When someone says it to you, reply with something like, "You too," and mean it.
The world may be a better place if you start saying nice things to people in a meaningful way.
If eventually everyone says something like this and means it, then maybe we can all stop saying it because it does get a bit tiresome after all, doesn't it?
Have a nice day. No, really.
