@Crunkle_Foreskin yea I know this behavior very well. It's not pleasant. In fact, its very frustrating.
Maybe he is very busy, and doing all kind of stuff as the same time. Causing to lose focus and patience.
Some chit-chat might work.. You also can just ask him DIRECTLY: Do you want to share something with me? (maybe there are other things going on? Maybe even not work related).. Or: Why don't you think my concerns are invalid? And/or: Should I change my communication with you?..
