Are you a 'saint' (question about nuisances)?

In research results, many times you’ll find that an X percentage of people get annoyed by certain behaviour (like: 80% of questioned persons hate people who throw garbage on the streets I assume then that those 80% don’t do it themselves, yet the streets are full of trash).
What I want to say is: people get annoyed by certain behaviour, but clearly some are guilty of doing those deeds themselves or so I believe.
I hate people trashing the streets with empty cans or wrappers, and I never do it myself.
But also, I don’t like it when cyclists cross the (red) traffic lights, yet every now and then I am guilty of doing exactly that.
So, what is something you think is annoying/disgraceful, but, you have to admit, you do yourself sometimes?
