i experience not so much of an impermanence i’d explain it more as if someone hasn’t been around in a while ie my parents when i am at college my initial brain response is ‘oh they’ve never done anything for me’ but it’s like i have to double take and force myself to recall this happens on a smaller scale too so i could see why having the picture in front of you to trigger memories would help and be easier instead of having to have the executive function to double take at all times
