My hypomanias present with extreme interest / obsession in whatever flavour of the month hits me...

Once I come down I'm no longer remotely interested nevermind fascinated by the previous hobby or topic....

My dad always rolled his eyes when I suddenly had a new interest, bcoz he knew it was gonna cost him and sooner rather than later I'd just drop out of whatever it was without any reason other than "I dont feel like it" or "Its boring"....

I've come to understand as an adult though, that its just the nature of the bp beast
