I have a peer who I think should take a leave of absense.
What makes you think they should do this?
I think he should take some time off from his responsibilities. He takes drugs and does lots of bad things to cope.
I agree with you. Taking time off to mentally reset and recharge is important so you do not slide into bad habits.
I think he should be in jail for his bad habits.
I hope your peer doesn't go to jail, but it definitely sounds like they need help and them taking leave is a good thing if they need it. People struggle in ways we might not know about and hopefully you can be supportive of what they are going through.
