There are always unknown factors in any relationship, friendship or acquaintance. We can never know the full sum of another person's experiences, or how these have shaped the way they see the world.

More than anything, the next time I feel wronged or judgemental - I'm going to make more of an effort to give the benefit of the doubt. The world isn't black or white - the shades of grey seem to increase with every day.

Really, really sad.
