Haim sisters went into self-quarantine in mid-March -- in their separate but very close Los Angeles homes -- the youngest, Alana, has been craving the bar and bat mitzvah circuit.“I’ve been very nostalgic for my 7th grade year,” she says over Zoom, sitting in between Danielle and Este. “I have never partied harder than that year.”It makes sense that, after nearly three months of isolation -- during which Alana admittedly bought inflatable guitars and has been playing a lot of Jason Derulo and Flo Rida -- she’d be yearning for the days when her only priority was to “put down my Shirley Temple and get down on the dance floor” as soon as Ciara and Missy Elliott's “1, 2 Step” came on.
