I pretty sure they sell adorable Valentine's cards in the store. I'm pretty sure if you plan to make 23 Valentine's day cards you should buy supplies, other than just candy. I'm also pretty sure if you need to make 23 Valentine's day cards and you don't have the supplies, to make them the way you had planned, you should start before 10:00pm.
Knowing and doing are two very different things. I hope Noah is having a wonderful Valentine's Day party today at school and I hope next year I remember they sell Valentines at Target.
