Its so strange

I was born Thursday, December 31st, New Years Eve, 1987.
My brother was born Friday, January 1st, New Years Day, 1999.

He was born the day after my birthday, the weekday after me.
11 years later.

My sister was born on Wednesday, October 28th,1992.

She was born on a month thats earlier in the year than our ones, on the weekday before our ones.

So odd.
She is the odd one out too because me and my brother look like my dad and she looks like my mother.
