Hello,
I started working for this company 3 months ago. I work in a large open plan office within which there are multiple different teams. Last week I had a training day and sat with a woman from my team who was sat with two people from another team that she is friends with.
I spent the day in this group of 4 and went to lunch in this group of 4. One person was a guy about my age (early 30s) that I got on well with and had a laugh with.
A few days later I saw him again in the kitchen and had a chat and he said he was just about to go for a walk around the town (job is sedentary) and did I want to join so I agreed.
Then yesterday the guy messaged me on the work intranet private messaging system and asked if I wanted to go for a walk again at lunch.
This guy is in a long-term relationship. We get on well, lots of banter and similar interests in terms of music, exercise etc. I could see myself being good friends with him but do people think this is inappropriate?
