Driving Me NUTS

There is a man who walks by, I feel like every day (even several times a day), honking this irritating bike horn.  It literally infuriates me because it drives me mad and I don't know what to do with myself.  And yet, I fight every urge to yell at him like an crass American because I think he's collecting old newspapers or something.  I think that means he's the recycling dude that I can't hate despite his horn.  I don't hate the man, I hate the horn!
