Well I don’t know the name of the current older friendly neighbour living directly across from me for the past five years . She knows mine and mentions it every time she says hello. Was just yesterday evening she knocked on the door to ask who had drilled a hole in her patio deck, we were out chatting for maybe 20 minutes. Too much time has passed at this point to ask names. I just say hello and have a nice day.
Suppose I could fake a head injury, claim my long term memory is temporarily damaged for the opportunity to have her “remind” me of her name.
