The longstanding fight I have with my sister is whether birth order impacts personalities

I am the youngest

Every youngest child is chaotic and incapable of irony because everything they do is for themselves since their parents got tired of parenting after the first few kids (shout out to when I was in high school and read Name of the Rose by candle at night cause I wanted to feel like a monk and didn't tell anyone until now)

Every eldest child becomes an adult and is dedicated to self enrichment after having had to help raise their younger siblings

My sister agrees but thinks that youngest children are attention seeking which is so rude of her to call me that

Like why would I constantly be working on publications and also taking on new roles for recognition? For validation? So rude
