I'm a good citizen (some-of-the-time) who follow most-of-the traffic rules,when on road ;)
I wear my helmet,wait when the traffic light goes red & I don't,I repeat
I DON'T HONK 
unnecessarily and I just can't take it when someone does.It irks me to the core,when one honks for no reason.They honk when signal goes red (as if it would change to green on honking),they honk if somebody behind them honks,they honk at every cow/dog/man/tree on road,they honk just to show off their 'honking' skills,they honk if they are bored,they honk just to make sure they are not deaf,they honk to make very sure if others are not deaf ,they just honk to honk for no reason or rhyme!!
*Sigh* Only if noise could be seen and not heard ! :)
