Today I had a dishwasher delivered. The guy was really nice. My son and my baby were here and my son and I were sorting out his school stuff. I asked him if he had kids, just making conversation about all the stuff they need. He doesn’t have any but seems very much like a “dad” type. He was great explaining how to use the new dishwasher. He asked if there were three and a half people in the house, because we were talking about whether it would be good for me to set the dishwasher to half washes. I said no just two and a half so he knows I’m single. We were also talking about how bad some landlords are because I’ve had a lot of trouble with mine. He left his card in case there are any issues. I’m wondering if maybe he was keeping the door open for contact because since I’m renting things like that would go through the estate agent. My friend said maybe I should message in a few days saying thanks for his help and it’s working well or something like that. We weren’t flirting at all just had a nice chat and we inadvertently found out that we were both single, or at least I am. I assume he is because no kids and he didn’t say anything like hopefully soon etc. Would it be weird if I messaged him?
