TAKE THE PICTURE.
Take the photo.
Don't just say "oh, we gotta take a photo together".
Then forget to take the photo.
Then say "oh, we'll take it next time". Last year I wanted to take a photo of myself, my best friend and my daughter at our favourite vacation spot. It's a place my best friend and I spent many wonderful vacations together during the summer.
I wanted a new memory of the two of us with our newest little vacation buddy.
Then we forgot.
Then we said next time.
Then there wasn't a next time.
Always, take the photo.
