Another HIPAA question

Maybe 7-10 years ago, I had occasion to visit, in the course of my work at a hospital, a patient who had been very special to my Mom in their childhood through teen years. I can't remember how the topic came up during my time with the patient, but it did, and the patient, I'm rather sure, said something like, "please tell your mom hello", and I likely asked if it was okay for me to tell my mom that I met the patient there, at the hospital (though now I am freaking out and trying to retrace my steps, or my words, since I can't remember). When the patient died, we (my mom and I) attended the funeral, which was surely posted in the published announcements. I think maybe the family remembered me, having met me at the hospital, and maybe said something like that when my mom was there. I dunno - would all this be alright if the patient said that I could indeed tell my mom that I met the patient at the hospital?
