<human>: Provide a brief overview of the text.

My office is currently going through a space crunch and has placed a senior worker in my office as an emergency measure. A pairing between a younger girl and an older guy would normally be really weird but management contacted my specifically to tell me that it was an emergency short-term thing and that when I made it was over I would get a raise. So, weird situation but I couldn't complain about it in concept.

He is an overweight man in his 40's. Normally he is very congenial and professional so under normal circumstances things would be fine. I should also mention that in all other areas he appears to be well-kempt and have good hygiene. However...

A few days ago he broke wind really noticably (smell and sound). I did not acknowledge it because I did not want to make it awkward. After that incident things have been spiraling out of control in that he is farting with increasing frequency. I don't want to bring it up in case it's a medical issue or something but it makes working in the office weird. He also must know that he's doing it since occasionally he add some little commentary like "whew" or chuckle at it or something.

I will likely remain cubicle mates with him for a few more months. What should I do? This seems like a weird issue to bring up to HR but I also don't know who else to talk to. Additionally, it's unlikely that anything will be able to be moved around due to the aforementioned space issues. Suggestions?
<bot>: New cubicle mate farts nonchalantly leading to smell and sound issues in the work area. How should I address this?
