My massive box made me a friend

So I'm not that bad a big sis. After making a treasure hunt that led to nothing and then hiding his birthday cards, I did then do this for my brother. And whilst I was putting the finishing touches to said box in the Hopwood services car park, I made a friend with a passerby. A rather helpful truck driver helped me stick the lid together, thank you random truckie, for your help and for not knocking me over the head and dragging my off into your cab. Then again maybe you were more scared of me, you did seem quite perturbed.
