The name of the word

Chilly morning with bright blue sky. Lovely leaves. I walked out to Griggs listening to Sandman. It's been a stable week so far. DH has ridden to work three days. I spoke to a counselor yesterday. I talked a lot. Not sure what I got out of it. Next week may be better. I'm glad I'm doing it though.

New person started on our team. I'm going into the office next week. That will be new.

Birthday planning is afoot. Fucking plague.

"Um. What’s the name of the word for things not being the same always. You know. I’m sure there is one. Isn’t there? There must be a word for it… the thing that lets you know time is happening. Is there a word?"
