Honestly, I am unoffended by that dynamic in my house. Our difference isn’t as great - my 5’5" to his 6’2" - but I just laugh and tell him to move when he tries to scrunch down to get things, and I sigh loudly and stare at him while stretching my arm up if I don’t want to climb for high things. We’re goofy like that, though, neither of us take it seriously and he teases me right back.
