Knocked over

As with any kids, birthdays are a big event. They are asked about repeatedly as they await the big day. These muffins are no different. Except for Ty. He wants his birthday picked up. Conversation went something like this: Ty: Mommy, when is my birthday?
M: in October
T: but I want it picked up!
M: what do you mean Ty?
T: I want it picked up!
M:(clueless at this point) Ty, we will celebrate your birthday in October.
T: but I don't want my birthday knocked over.
M:(now understanding and unable to hold back the laughter) oh Ty! Your birthday isn't knocked over. It's in the month of October...(sparing you the lengthy explanation)... So when October comes, we will celebrate your birthday just like we did for your brothers. Will that be ok?
Ty: but I don't want it knocked over! I want it picked up!
Clearly one, two, three and four explanations have not been enough as he is still bothered by this. A couple days will pass and I'll think we are ok and then out of the blue... "Mommy, is my birthday picked up yet?"
