How about I tell my dad he's too old to find a job he really wants to do?
Are you serious? Why would you tell him he's too old to find a job he wants?
I don't know. I just know he can't find a job.
It's expected to support family members when they're trying to find work. If they don't feel supported they might end up not coming to you later on when they are seeking help. This can cause your relationship to worsen in the long run.
No one's saying I will have to help them. Do you want my dad to keep being unemployed?
You shouldn't be so discouraged that your dad might not find a job. You should support him so that he can get the job he wants. Maybe help him rework his resume.
