A user reported the disappearance of an SD card from their camera while working tech support at a conference. The card was confirmed to be in the camera the day before, leading to two main theories: either the user removed it unknowingly or someone else took it while the camera was unattended. The discussion explored the likelihood of theft, with participants sharing anecdotes about similar experiences and the nature of memory cards being small and easy to steal. Suggestions included checking for on-board memory in the camera and considering the possibility of having left the card in a computer or bag. Ultimately, the user discovered the card was in a laptop they had been responsible for, highlighting a lapse in memory rather than theft. The conversation also touched on the peculiarities of the conference setting, where the user was the only male among attendees, leading to humorous speculation about the circumstances of the card's disappearance.
