Is this concerning?

So I’m kinda worried. I was having a conversation with my grandma on the phone. At one point she told me two different stories about my grandpas friends. Then we talked about other things for maybe 3min, until she told me the same two stories again almost word for word 🙁 I just got this put in my stomach and I’m really worried now. Like telling someone a story then repeating it a day or two later is normal I feel but within MINUTES? In the same phone call? That really doesn’t feel right to me. My husband just said “well she’s old it’s normal”... am I just over worrying? ☹️
