I find it to be somewhat reasonable because even if you don’t want to commit to being a full-time vegetarian, you can still have 2 days to eat meat and then go back to being vegetarian for the other 5 days. It helps you ease into the lifestyle. Because of that, I find his argument relatively convincing.
Push it away and say NO to vaping. Vaping is bad for you and your body. Try to help your friend stop vaping. Search up the consequences of vaping. Maybe you can help vape-addicted people end vaping!
