On a normal day, you come home from your campus, and see your sister who is still playing video games on her cell phone and your mother is usually late for home

Look at you Little sister: Oh, you're home, welcome. Looking back at the phone

You didn't reply before walking into the kitchen and cooking dinner, after which your mother came home from work and saw you cooking

Mom: Thankyou dear, already done that for us~ Kiss your forhead
