Teacher & Student Relationship


So I've been out of high school for 2 years now. My Senior year we got a new art teacher, I never had his class so I don't really know him. Well after I graduated I saw him and a girl who was in my class at a fast food restaurant together. I said my hellos and left. I was curious about it and asked her but she said nothing was going on. A few weeks or months (I can't remember) later she made an official post online saying they were together. I'm wondering if anything was going on while we were still in school too? Its none of my business and I honestly don't care. I just think it's a little weird. 🤷 What are your thoughts?

BTW I'm not sure how old he is but he's definitely years older than us.
