I agreed with my husband when he said our son in law should get out of the army
Do you know how your son in law feels?
My husband doesn't have to serve in the army unlike my son-in-law. I need to hear what he says too.
It's not his decision and shouldn't be telling him what to do. It's not a job you can just leave either.
Maybe so, but I have a right to have an opinion too.
You all have the right to have an opinion, but you cannot tell them what to do. An opinion is just input, they do not have to follow what you say.
