5T doesn't get anything done during @LeTour de France, so this is totally understandable. No apology necessary.
Apologies for slacking off last week. This is the cricket season. We are not being attacked by crickets ๐Ÿฆ—. Cricket is a game ๐Ÿ, and a world cup is on. For us itโ€™s bigger than football world cup ๐Ÿ‰, formula one cup ๐ŸŽ๏ธ, super bowl cup ๐Ÿˆ and quidditch cup ๐Ÿงนcombined ๐Ÿ†๐Ÿ†๐Ÿ†๐Ÿ†๐Ÿ†โ˜บ๏ธ

75 years ago today the first atomic bomb was dropped over Hiroshima, instantly killing tens of thousands of the city's inhabitants. Setsuko Thurlow, then 13, was one of the city's survivors. In 2017 she jointly accepted the #NobelPeacePrize in Oslo on behalf of @nuclearban.
