#4 You know you're a vaper when you carry extra disposable e-cigs with you so you can hand them to family & friends so you don't have to smell their second hand smoke at gatherings LOL (haha I did this at a New Years party, a bunch of us sat around the poker table vaping the PVs and disposables I had cause we didnt want smoke in the house and it was too frigid to go outside and smoke)
