I kind of just realized but at the same time already knew this- I still have a hard time looking a photos of my parents. It’s like some kind of reminder that they were here physically and now they are not. Photos of my parents when they were younger I somehow have less emotional attachment to. I think because I wasn’t here yet I don’t have a memory of them being or looking that way, so it hurts less.
If you’ve been wanting to put up photos of your parents but are having a hard time, try putting up a photo of them when they were younger. It may bring you more joy than pain and is worth the experiment.
