I looked up “call in” in the online dictionary yesterday when I received that msg. I found one of “call in” meaning is “visit”.
Thanks for everyone's discussion.
Today, I confirmed it with the office coordinater, the policy was changed
last Friday when I was off. We donot need to go to the office in person but discuss with the office
nurses via in-house phone. That is why she used “call in” yesterday.
Sorry for the misleading.
I guess booster shot affected my train of thought yesterday.:)
