Why don't you...

They will tell you are gross for smoking a cigarette but they will drink two liters of wine in 30 minutes. They will tell you they never took a sleeping pill, god knows if people that does it  is insane  but they will  later run to their mistress for an intense session of pain . They will point your vices everytime just to forget about theirs. Be proud of your vices and of course, try to give up to them.
