According to Sugar

At the park this weekend, the following conversation occurred after dinner and playtime, on the walk back to the car:

Wow...that's a huge stick there Sugar.  It's bigger than you are!

Call me Grandma please, Mama. 

Okay, Grandma.  What are you planning to do with the stick?

It's my walking thing.

Ah, I see.  Grandma?

Yes, Mama?

Why do you need a walking thing?

For my yogurt.
