Fine: I'm not interested in talking to you on your way back from a date with someone else.
Not fine: I didn't need to answer because isn't this what you wanted, to be separated???
The first is a simple, direct report about you.
The second is passive aggressive, fight baiting, R talk.
Better: I often screen my calls. We should figure out a system for emergencies. Lots of people text 911 in case of emergencies, so I guess we could try that.
