I've been an advocate of the wrongly perceived understanding that someone knows how you feel or what you're going through. Even if they've been through it themselves, no one, and I mean no one, can understand what another person is feeling or how whatever they are going through affects them. It really irks me when someone says 'I know how you feel' or 'I know what you're going through' because they don't, simply because they are not you. Everyone feels differently, everyone experiences life differently and the only person who knows and understands what you are going through, is you. Good call on that video, very poignant.
