I'm currently only going to the office 2 days a week. The rest of the time, I work remotely from home, so sometimes, I don't get some office news.
One of those days, I came in late, 9 am instead of 8 am, which isn't a problem because I then stay until 6 pm instead of 5 pm. And this intern (let's call him John) told me: "You are late"; which I thought was very rude and I almost said, "Well that none of your business" but when I saw he was a new guy, I just said "Yes, I know", marked my entrance and went to my desk.
Then, next week, I realized that he had the tendency to say the obvious. We have been under frequent blackouts and every time it happened, he said very loud "Not again". I know blackout are annoying, but I just take a book and go to the window to read while the electricity return.
Also, it seems like he doesn't understand sarcasm. I was talking to a coworker during another blackout and he came and this conversation happened:
John: "This is unfair".
Me: "When did you arrive?" (and move my hands showing around).
John: "I arrived at 8:30"
Me: "I mean when did you arrive in this country because those blackouts are common and you already should be used to."
John- Yes, like 8:30".
Now I'm wondering if John is like Sheldon because I had other similar interactions and I feel like I'm in an episode of "Big Bang Theory".
The thing is because I'm not in the office, I don't know if my boss said anything when he introduced John and not sure if I should ask. I'm not sure if have to be more tolerant when I hear something like "You are late" or when he is loud and more careful of not doing sarcasm around him.
Should I ask my boss about John situation and if there is something I should know about him?
Edit: I'm not in charge or work with John, but he is seated next to me and even when those loud complains are middle annoying, I won't call him out about it. Also as I said only at office 2 days so doesn't affect much. Now even when I describe the event cronologic those weren't even an issue until I did the light sarcasm and my surprise by his response trigger an internal analysis of everything that happen previous weeks.
