What makes an Auntie?

B went running to the fence shouting Auntie, Auntie Auntie Barb. I wondered what makes an auntie. So I asked.
Apparently, the criteria is quite steep.
1) you have to be family. If you are not family, you have to come over regularly so we can audition you (bmk)
2) you have to be red (alk)
3) you have to be nice and loving (bmk)
4) you have to have games on your phone (bmk)
5) you have to be a girl (alk)

Me: So... who are your aunties?
Rachel is the most auntie. Then we have T, Elizabeth (with straight hair just like mine, bmk), Auntie Alanna and Megan.
Me: Any other Aunties?
BMK: yes! Barb, Michelle and Kassie!
