Want to start collecting MH doll but i'm kinda afraid

(Idk if the flair is the right one...and i'm from Argentina, so i'm sorry for grammar mistakes)

... This is prob the dumbest post on this subreddit, but basically: I want to start collecting monster high dolls because it was my childhood...and i love the lore, but my family and sometimes friends usually come to my house and I KNOW they will make fun of me for being "childish". Should i hide the dolls, directly stop the idea, or just do it anyway?
