They like lorry.

So. I was driving home with my mum from Curve just now. We were talking about something(I forgot what) and the conversation was a bit tense. Suddenly, I saw a few stray dogs chasing and barking at the lorry which was in front of my car. Then I said :

Me : Eh, why they chase the lorry and bark at it arh??
Mum : They like lorry.
Me : ….

My mum is so cute right(I wish)?
