I saw a headcanon about Yondu & spun it a little. Lets say the collecting trinkets is a cultural thing - his kind exchanges them as some part of the bonding process, like an "im interested," an "im claiming you as mine", or a proposal type thing. Reader, whom Yondu adores but hasnt done shit yet, sees a cute trinket, snatches it, & presents it to him. He automatically goes all heart eyes and melts cuz he thinks reader just pubically declared him theirs. Cue him courting and them being confused.
