Today when I woke up, I freshened up and after that, made breakfast for my dad and siblings. After that, baba went to his office and my brother went to university.
Then, I used my mobile for a while and later i learnt fifteen idioms with my elder sister.
Then my mom came back from school. I made tea for her and my sister.
Then I studied from 4 to 7'O' clock.
Then I had my dinner and went to my room to sleep.
The word "elder" is very formal; I would use "older" here.
My older sister is two years older than me.
