@RickiTarr When I fail to act and end up feeling like a gigantic arsehole. Ex.: Sitting in a cafe near the door having tea. A fellow in his 60s came up with his elderly mum in a wheelchair. He struggled around trying to get the door open and... I just sat there watching. Why? I have absolutely no idea. To be fair, no one else helped either. Once he got the door open my delayed reaction kicked in and I held the door for him. But jeez, why didn't I help when I first noticed he was struggling?
