I only have my own perceptions and experiences to base things on. There is no way to know their experiences, thoughts, feelings, or perceptions to shape their situation. I can ask, I can possibly surmise some things (which can cause problems), but still, I can only poorly attempt at understanding. I will however still try to at least empathize were I in a similar situation, which still does not come close to their own circumstance. So I can never know what someone else is gong through and will not pretend to actually know their perspective, yet will still try to understand it but I can't know it.
