Understandable at any age!
Like I said - asinine!
My 14yo considers herself and emerging-adult......I think of her more a brat! She did however get on an airplane in Norfolk, change planes in Baltimore and arrive safely on her own in Tampa yesterday. I wanted to cry when she walked passed those TSA agents yesterday. One o them smiled at me and said “She’ll be fine, Mom.”
Congratulations! They can be amazingly competent, while at the same time being impossibly bratty ;-).
