I go to a gym that isn't the closest to home but it's convenient for me for work. This morning I swam and when I was in the jacuzzi one of my husband's pub friends walked past with a woman I didn't recognise - he is married and this isn't his wife. He had his hand on her back and was guiding her. I didn't know he's a member there, never seen him there before but I don't suppose that's unusual.
Later I was in the sauna and he opened the door and held it for her to come in and again put his hand on her to sort of guide her in. He spotted me and quickly looked away and said to her 'I'm going for a swim actually. I'll meet you out the front'. She seemed a bit puzzled but stayed for a few minutes.
By the time I got home he'd WhatsApped my husband to ask if he knew a physio - he said his training partner had pushed him too hard at the gym this morning and he'd injured his shoulder. They have never texted each other individually, and my husband wouldn't be anyone's 'go to' for sports physio advice. They're just both part of the same group of middle aged men who sometimes meet in the pub. My husband didn't know he was training for anything, and didn't know he was a member of a gym.
I used to sort of know this man's wife years ago but just to say hello to when our kids were in primary school. We live in the same village. I can't just contact his wife (or him) and ask what's the deal with the 'training partner', can I?
I have to keep my nose out, right? I don't have enough evidence to speak up, I could cause a lot of unnecessary damage based on nothing but a brief observation and an out of the ordinary text message. It was such an unusual series of events though that I'm convinced that something is going on and he's building a cover story (and I'm not generally an imaginative person, definitely not a fantasist type).
