"Be soft. Do not let the world make you hard. Do not let pain make you hate. Do not let the bitterness steal your sweetness. Take pride that even though the rest of the world may disagree, you still believe it to be a beautiful place." - Kurt Vonnegut
If you must assume, choose to assume that we are each giving our best and forgive another for not always meeting your expectations of them. It can't hurt, and it most definitely could help all involved.
