Let go because things aren't the same anymore. People simply grow apart, which is perfectly normal. When you realise that you want different things, no longer share the same interests, no longer understand, and no longer connect. It's a matter of accepting that it takes time to let go, rather than holding on to something that just can't be brought back, was lost a long time ago, or perhaps, was never really there at all. It's difficult to hold on to people in life, but remember you are destined to meet different people along your journey who will bring you happiness, sorrow, pain, and joy. (c) Truth Slap
