This weekend Dad and I took you to the playground. Dad was pushing you in the swing when a little 3-year-old boy came running up to me, yelled "BISTER!" and smacked me on the cheek with a chocolate cupcake. His Dad immediately ran over and told him to be gentle, at which point the boy yelled "BISTER" again, cracked up, and patted my cheek gently. Then he sat in my lap. His Dad looked a little surprised, but I didn't mind. He was very sweet and cuddly and we sat like that for a while, as he continued yelling his strange word and collapsing in giggles. No one knew what he was saying. When he got up and wandered away, his 1-year-old sister climbed into my lap.
I was telling Aunt Lizzie this story the other day and when I got to the "BISTER" part, you started laughing and would not stop. I don't know what that word means, but it is apparently some hilarious code word known only to children.
