I can sing and dance, unlike my brother.
I can be the worst person you'll meet so be ready and don't fall for my nice acts.
I can think about what to do-- in reality, it is really hard.
I can give her money but she will be used to it and abuse my kindness.
I can't be a doctor because I am afraid of blood.
I can be a perfect person for you my love.
I can be your companion whenever you need me.
Hope it helps. :)
