The Life of a Politics Student

Me: Mum, have they sent my polling details home yet?
Mum: Huh?
Me: The coming election, have I received anything yet?
Mum: Oh yes, that came last week.
Me: But Mum, I need a postal vote because I won't be at home, can you sort it out for me?
Mum: Oh Thanh, why do you worry so much?
Me: Because I want to vote, Ma.
Mum: You know, it doesnt matter if you don't vote.
