Should I be suspicious about this? DH dropped me off for an hour's appointment, then he drove to drop off something at a friend's house, did some shopping, then returned to pick me up. When he picked me up, the passenger seat had moved. So I said to him that the seat had moved and he replied that was probably when he moved it looking for something under the seat the other day. However, when he told me previously about this he had said he'd moved the driver's seat. Also, I hadn't noticed the seat had changed position on the drive in to the appointment so it must've changed during the hour or so I wasn't in the car. The mechanisms are electric but it was the seat extender that had been pulled out, when you want more support under your legs, and this is a manual switch you lift and pull so it couldn't have been anything to do with the automatic seat settings.
I feel his explanation is a bit off because he didn't give any reason why or how it had moved during the hour but then if someone had been sitting in the passenger seat then why wouldn't he just say?
This isn't the first time the seat has changed its position but all previous times could be explained by him giving someone a lift so I've never mentioned about the seat moving.
