If you know if it's someone's birthday and you will have a party for him/her! Maybe you do it on a doc but if you don't have it, you can't do it there! If so, have a birthday party here! Post something like:
Happy birthday ____! Let's have a birthday party!
Or something like this! The have a party! We could have a party now and not just a person who say "Happy birthday"! It will be fun for the people who have a birthday!
It must be hopscotch related, like make birthday card at hopscotch! Don't do it to crayzy!
