Hello, I lost my Dad only a month ago and I don't think you should feel at all foolish about anything that happens or that you do, that involves remembering the person you have lost. It is good that he is still in your thoughts so strongly, so please try to make a positive out of things like this. Even if you feel part of you has accepted he is gone, there is nothing wrong with another part of you still believing he might somehow still exist. That latter belief is the only thing giving me comfort at present. My Dad isn't the only bereavement I've suffered, I had another in 2015 and another in 2004, and part of me still believes those people are not really gone.
