When I got to my office yesterday, everyone was in a chaotic atmosphere. So I asked my colleague what was going on. My colleague told me that a sparrow came in from the window and it was flying around in our office. I thought one shouldn't chase after the spparow because especially birds are sensitive. But men in my office were chasing it around and trying to catch it. As a result, the men got tired of chasing the sparrow and gave up trying to catch it. After a while, we kept our windows wide open and it went out on its own.
