Yes, I still ask myself what moment I should choose.
I am leaning more and more towards when I have trouble recognizing one of my relatives, especially one of my children. I know that it's going to happen, and for me, that's the last straw. You have to have a cut-off point somewhere, but it's not easy.
That's my opinion right now, but to be honest, I have to admit that I haven't yet made up my mind.
