Conversations With The Red-Head

The other day I was leaving my sister's house. This is the conversation that I had with B:

Me: I'm leaving. Bye.

B: Bye Auntie Laura. I'll miss you.

Me: I'll miss you too.

B: I'll miss you more than you'll miss me.

Me: I'll miss YOU more than you'll miss ME.

B: Are you calling me a liar?
