In Boston, anything to do with Patriots tight end Rob Gronkowski is big news. Usually it’s somber: a strained back, a tweaked ankle, or a torn ligament. But on some days, it’s just “Gronk being Gronk.” Friday was one of those days, as Gronkowski took to Twitter to share a bit of how he’s spending his offseason. Is that tweet news? Probably not. We all go food shopping all the time. But you should take a second to think about what a trip to the supermarket with Rob Gronkowski would be like. ESPN thought about it when they did a feature on him in 2012, and they learned what you’re probably realizing right now: going to the store with Gronk is... different.
