When my Gma passed last year, it was hard bc she suffered from dementia the last decade or so, and it really clouded how she really was. When she passed, I got to work on her photo collage board and it was so therapeutic. It brought back waves of memories of how she truly was before she got sick. And now I carry around a photo of me with her - she's rockin some purple skinny pants plus heels and I'm 5 years old with the cutest hairstyle. But that's how I want to remember her and I smile anytime I see it.
So, that's my suggestion to you - pick a photo that you think H would love to remember his friend by. The happiest/funniest/best memory.
I forgot to post a FU. Thanks for the reponses everyone
I decided that I'm actually going to make a photo book chronicling (is that a word?) their time together. I was going to include pics of all of the friends in that group and make a copy for everyone. I need to get busy this weekend!
