Mostly fired and can't talk about it with parents

I've done a good job saving over the years, and at 52 am mostly fired. I was also laid off last year from my job so haven't been working since than, and mostly don't need to. My dad is always asking when I'm going to get another job, he doesn't think i have enough to support myself, which i do. The issue is if they think i have money, they will ask for it, and I can't really afford to fire and give them money. Its really annoying and heartbreaking that i have to not tell them anything, and just pretend like i'm looking for a job.

Has anyone dealt with this, and advise on what to do or say?
