Why is this such a classic identical twin move

So I'm 16 and an identical twin, older than my sis by 7min and also oldest of 5 including me + twin but anyway, why do parents name twins rhyming stuff so much! Like I'm tired of the 'oh you're Mea and Lea, that's so cute ahhh!!!' that I get AS A TEENAGER STILL. Like yes we are twins but Lea is like, my OPPOSITE!!
