You're a different person now, it's just sad because I miss you a lot. Strangers can become best friends just as easy as best friends can become strangers. Friends and family members evolve over time, we all do, so this is a sad but true fact of life.
So deeply felt is a burden, nothing else. To feel so deeply makes me frown. Deeply felt is a sin. Feeling deeply a tragic curse. To feel so deeply as to be scarred by everything left to be just a mark.
