At approximately 11:38am Cupertino time on Wednesday, Apple CEO Tim Cook posted a cryptic message on Twitter reading only โ€œ๐Ÿ˜€.โ€ It was quickly deleted.

What could the man in charge of the worldโ€™s most valuable brand be trying to say? Was it a mistake? A test? Did the tweet herald a new, Apple-developed two-way neural interface that feeds users pleasant imagery until their mouths are contorted into painful rictus grins, a caricature of genuine human joy? Maybe it was just a ๐Ÿ˜€ day.

We have reached out to Apple for comment will update this post if and when we hear back.

Update 8:45pm: Wednesday evening, Gizmodo received a revelatory email titled โ€œI know what the Tim Cook smile means.โ€ According to the tipster, who worked for Apple for several years, Cookโ€™s tweet was likely intended as โ€œa private response to someone and he accidentally made it public and then caught his mistake.โ€

โ€œI know a co-worker, about two years back, who wrote Tim to tell him about a really great interaction my co-worker had with a customer,โ€ writes our tipster. โ€œHe was surprised and delighted to actually get an email back several days later. He shared it with several of us. The response was a smile.โ€
