My childhood lego collection (as far as I can remember; I can't verify because I didn't take any of them to college with me):
Stephanie's Pizzeria (41092)
This was my first-ever lego set of my own; I remember getting in trouble because I stole some of my dad's 80s spaceman legos to build a house for the minidoll and her stolen 80s spaceman boyfriend lol
Heartlake Lighthouse (41094)
This was probably my favorite out of all the sets I ever owned; I would rebuild it constantly and I think I even memorized how to build it without the instructions. Honestly the remote lighthouse ice cream shop vibe was so on-point
Emma's Creative Workshop (41115)
Adventure Camp Rafting (41121)
Livi's Pop Star House (41135)
I got this one at an actual Lego store on a sightseeing trip to [major city name redacted] with my own money even (50 dollars was an absolute boatload of money in my 10-year-old eyes) and that automatically gave it a coolness factor that none of my other sets could even dream to live up to.
Heartlake Gift Delivery (41310)
Mia's Bedroom (41327)
I was so angry when they redesigned all the characters in 2018 (when I was twelve) that I literally stopped collecting Legos once they did it (and would rant about it repeatedly to literally anyone who would listen), but some well-meaning relatives didn't get the memo and gave me this one and I despised the rebrand so much that I refused to incorporate it into my main legos and hid it in one of my desk drawers for like two years.
