I also say “thanks for the update” or “thanks for the head’s up!”
“I really appreciate the head’s up!” also a classic
If I haven’t gotten back to someone in a swift enough period (i.e. one work day max) I say “thank you for your patience. after some consideration, I have decided…”
don’t apologize for piddly things!
thank you > sorry
I need to remember
thank you > sorry
Thank you for waiting for me > sorry for being late
Thank you for helping me/for your time/for listening to me > sorry for bothering you
Thanking someone when they do you a favour > apologizing for your existence
This is especially hard when you haven’t been taught that people need to respect your limits, but with a bit of practice you can absolutely get there!
