This happened long ago and it is still relevant today.
Me: Hmm, a pack of peanut biscuits.
Mum: Do not open it, wait till the biscuit tin is empty then open the pack. Otherwise, it turns soft.
Me: What about this plastic container?
Mum: Too small, it is not going fit in.
Me: Let’s try.
Mum: See I told you it is not going to fit in. The container is full and there are some pieces left in the pack.
Me: Yes, it will
Mum: ?!?!?!?!?
Me: I will keep them in a safe place
Mum, thinking she has an idiot for a son.
Me, ate the rest.
