Both of Them

Both of them have some similarity. And I’ve just realized it two days ago. When I was hanging out with my friends.

Both of them are second child from three siblings.
Both of them have same gender.
Both of them have different gender from their siblings.
Both of them love their family.
Both of them have same responsibility.
Both of them need to ask their mom to get permission.
Both of them usually broke their promise on the last time.
And both of them like to make me confused.
