Me: Let's use the new shampoo and conditioner.
Mum: Okay. Which one's which?
Me: Come here and I'll teach you how to read them.
Mum: Noooo.
Me: Come on, I'll teach you.
Mum: Blergh, I already know. How else do you think I bought all our previous hair products?
Me: Because you know shampoo stands upright and conditioner is upside down. I'll teach you.
Mum: Nooooooooo.
Me: Ugh, fine *passes conditioner* This one's shampoo.
Mum: I don't want shampoo. I want (Chinese word for shampoo).
Me: ... That IS shampoo! ROFL
Mum: ... Oh.
Me: So anyway, this one's shampoo *points at conditioner*

I wonder if she'll realise :L Mwahahahahaha!
