Do you answer your phone without checking caller ID?

3:45 am. My phone rings, and I answer. Work needs me to come in and deal with an outage. I am on a list of 15 workers in my area who can fix this, and my name is in the middle of the list, which means 7 or 8 people were called first, and didn’t answer the phone.
I have noticed my kids always check the caller ID before answering, and often brush off the call. I never do this, and always answer the phone.
Do you do this? Do you often regret answering?
