For Their Thoughts?
It may be too late this year for you to celebrate Give a Shiny Penny to the Third Person You Meet Today because 1) you didn't keep track of who that person is, or 2) you know who it is but you won't see them again today, or 3) you don't have a penny, much less a shiny one.
If you don't get out much and haven't seen many people by the time you read this, you may still be able to celebrate. Just find that shiny penny first and keep track of those you meet.
It doesn't actually have to be a shiny penny. Any penny will do. Eventually, after they discontinue and devaluate all the pennies, we may have to switch this to a shiny nickel. That just doesn't sound as good though.
See a penny. Pick it up. All the day you'll have good luck.
If you believe in luck, that's always a fun thing to do. Giving a penny to someone is kinda, sorta the same thing for them.
Even if you don't do the luck thing, picking up a penny is still enjoyable, isn't it? I bet you've never left one lie there after spotting it, have you?
