Ive had this issue as well. I find it happens when i leave my wifi and go to cell signal. Not sure if its the same for you. I dont think ive had it be almost a week later but its been a few hours or maybe a day

I have 2 from the same person.

1. “Why is it when hockey players stop on the blue and red line. The lines dont disappear”.

2. “The reason why there are train conductors is because they turn the wheel at the front of the train so they dont fly off the tracks on corners”.

Maybe not as crazy as some but it definitely made me think twice about other things she knew.
