I started a new job a few weeks ago. I work with a guy (20+ years older than me) who I worked with a few years ago in a different company. At that company, he was senior to me. At this new company, we are on the same level, if anything I'm slightly more senior (there was talk of me managing him).
We have a big department meeting on Friday. This morning he checked that I'd done everything I needed for it, and that I remembered it was happening. I had and I had, of course.
This is the third time he's done this. I've checked with our respective boss and he hasn't asked him to do this. I feel like he's trying to manage me, or doesn't trust that I'm good at my job.
Should I ignore this or call him out on it?
