I can't choose between Joyce, Hopper, and Mr. Clarke. They're all great people. Joyce is an amazing mom who loves her children so much and she's a good person overall. Hopper is a great dad who takes care of Eleven. Although they have arguments in the series, you can still tell he genuinely loves her and wants to protect her. Mr. Clarke is a good guy and a great teacher. You can tell he's passionate about what he teaches, and he cares about his students. :)
