Love this! No Pi day party this year... We had postponed the 3.14 one to 22/7 but nooooo, still not safe. Grumble rhubarb rhubarb. Haha...
My sister who was posted overseas a lot had her kids on 4/4 and 7/7, so they never had to worry about how the date was to be written! She wishes she'd done it on purpose, but she didn't.
