Two sisters, both older.
One is 16, one is 18. Myself, I am 13. They always complain and make me do anything that requires physical attributes, even though they are actually very strong themselves.
I have an older brother by 9 months (don't ask lol), an older sister and technically a younger half-sister, though in the UK most people don't care about half-siblings, since blood is blood.
I have 3 siblings. 2 brothers and 1 sister. We all live apart except for my brothers, who are together. Different parents. Ima call the by the first letter of their first name, same for the parents. We all share the same mom. 3 different dads though.
A's kids: me!
S' kids: T
C's kids: O and Z
J's kids (mom): L, T, O, and Z
Haha just made me think of when my sister pointed out in oldest to youngest, it spells TLOZ as in the legend of Zelda c:
