Happiest of birthdays! Hope it's a wonderful one! I'd love to know Sharon's first impression of real life Steve, not just the media hyped or second-hand Aunt Peggy version.
Assuming you mean Tales Universe, I think her initial impression was that he was kind of sad and lonely. She was watching him for SHIELD and he had a very regimented routine without a lot of human contact. I think the reason she made a point of “doing laundry” or taking out her trash when he was in the hallway was just to have conversations with him, so he’d have someone to talk to.
