"Mastered the art of writing?" I'm afraid that phrase has zero meaning, maybe less. I know of no serious writer who would claim to have done so at any age or stage of their career. I just finished my MFA and will soon be turning 70, and I think I may be nearing my personal peak, but some arts were never meant to be mastered.

Tessa doesn't bother me. Most of what she writes, I like. But she wandered into my house and started insulting my friends and family, so, no.
