Grumpy old man (at 25) syndrome

Yesterday I saw saw two teenagers sitting at a tram stop trying to eat one another. Maybe they were kissing, who knows - it was hard to tell.

Pet peeves

- People whose walking trajectory on a straight footpath takes on a 'S' type form - thereby infuriating people like me trying to get to our destination at some point this year...

- People who insist on pushing the pedestrian lights button when someone has clearly already done so. The worst offenders then repeatedly push the button to make sure it works. (What are you - five?!) The button is pushed. It isn't getting any pushed-er!

I saw this on the back of a truck yesterday which left me perplexed...

Warning: This vehicle in constant forward or reversing motion.

Since when do you need to warn someone that a vehicle moves forwards and backwards. My car does, I don't have a warning label - I thought vehicles were supposed to move forwards and backwards. Isn't that why you have a vehicle in the first place? So it can take you places? Irrespective of whether it does it backwards or forwards?
