Why????????????

Why is it that it is during the most difficult times of our life that some of our 'best' friends desert us??
Why is it that the it takes the most desolate, desperate times of our life to make us realise the 'real' worth of the people around us??
Why is it that it takes the lows of our life to make us realise the importance we have in some peoples lives??
Why is it that, over time ,some relationships attain the kinda magnitude you never thought they would??
Why is it that the ones closest to us hurt us the most??
Why is it that we hurt the people closest to us, the most??

Why are we not perfect?????
Why is life not perfect????
