On Saturday morning i missed a phone call from a friend who never normally calls me. By the time I saw the missed call on my phone, a good hour or so had passed and there was no voice message or text asking me to call her. So I thought nothing more of it, and carried on with my day, assuming that if it was something important she would have either called again or left a message for me to get back to her. Turns out that it was important, she had had a row with her DP and wanted someone to talk to, and friend is now in a huff that I didn't call her back when I saw the missed call. I've obviously apologised for not getting back to her but am curious about whether other people would automatically call someone back after seeing a missed call.
