I hate when girls call themselves auntie with their friend's babies
Is this happening to you?
Yes, my friend wants my kids to call her auntie, but she's too ugly to be related to my kids.
I can see how you might be annoyed with her wanting your kids to call her auntie, but likewise, you shouldn't call her ugly. Instead of calling her names behind her back, try asking her politely to use a different title.
I don't need to do that, I can just tell her not to come around anymore.
Auntie isn't the greatest term to use when you are not family, but you don't have to be upset with your friend over it. Calling your friend ugly is hurtful and mean. Drop the name calling and just have a chat with her about the situation.
