I'm going to be an inconsiderate vaper
What do you think about vaping in public?
I think vaping at public places is disgusting
You're right, it's quite inconsiderate to be vaping in the presence of others. That makes is strange that you want to do it.   It's best to be considerate of others and the second hand smoke they may have to deal with when you vape.
I'm going to vape right next to them anyway.
I do not see a reason to do that besides being rude.   You should think about how you would feel if someone did that to you.
