I live in a little culdesac and there's a guy opposite me with an Astra with a baked bean can on the back and he's always blipping it. It doesn't matter what time it is, he can't help himself. I can't help but laugh sometimes as it's amusing to think it's sometimes for my benefit as we both like cars. The only difference is, both me and Sabrina park our cars aiming in the right direction so when engine springs to life, it's immediately shoved into drive and we're away on idle... with, hopefully, no car alarms going off as we leave.
Some people just live in their own little bubble. I had the pleasure of house sharing for a few years when I first left home and came close to killing some of the inconsiderate f*cks!
