I went out to dinner and a bar with colleagues, 1 male who is a close friend, and 1 male who is an acquaintance.
So me and my close friend colleague have a habit of taking Photo Booth pictures. We take one together any time we can in restaurants/clubs so it’s routine for us - we meet up often and we’re in our 20s. We don’t usually go out with the acquaintance colleague, only in larger group settings (and with other women!)
On this day we took photos in a Photo Booth as per. But involved the acquaintance as to not leave him out. The male who is a close friend was out of view in the photos, you can just about see his beard and shoulders, so it looks like it’s just me and the acquaintance in the photo.
The acquaintance kept the Photo Booth picture on his desk at work like a decoration, and has now gone on annual leave leaving it there. Aibu to think that’s weird? People have asked me if we’re dating which we’re not. I just thought it was a harmless thing, no romantic interest whatsoever, he could have just binned it.
