Ooh with songs though i can conjure up loads of happy times. Weird how that works, off the top of my head I’m stumped, but with a song i can remember it all
They got away - built to spill, moto moindo - staff benda bilili: 2010 summer. Summer before my dad died. Went on walks with my parents in the woods, listened to my ipod while they walked ahead chatting to each other and id just feel fond and full of love for them. Nature walks are big in my family and i will always remember that summer fondly even tho i was like this guy at the end

and took the bus home at the end of the trail while my parents went all the way back to get home and told me off for being lazy
Also the summer of pokemon go in 2016 was great - drove to the beach with my ATDs one day and we were so excited to catch pokemon by the sea, went on a seaside holiday trip with my mum and brother and we had so much fun playing. I love pokemon so much and that game was the first thing i truly enjoyed in years at the time
