112. Stubborn
Steve was a stubborn child. He said no more often then yes, stomped his foot, pouted, and cried more crocodile tears than Natasha liked to recount. However, it was something she saw as being unique to him. Instead of getting angry and frustrated like most Mothers would have with their "terrible" two year olds, she was always calm and direct about what she expected and the disciplinary action she was going to take. To her, it quelled the tantrums much quicker and gave Steve something solid to grasp onto when everyone was leaving. Despite everything, he was still stubborn. But truthfully, that was how she liked him.
113. Skewed
Bruce was not a man well versed in discipline. His own upbringing had left him with no knowledge of how to discipline a child without using corporal punishment. So when Steve threw a fit over not getting to stay with him in the lab, he felt puzzled. He went with the only thing he knew, and set the child in the back corner. After some fuss, the boy settled. Yes, some of his views were skewed, but he still pulled through
114. Denial
Sometimes they all felt denial. For Tony it was being in denial that he cared about the smaller version of Steve. For Clint it was denying his feelings for Natasha. For Thor, it was denying that his brother was irretrievably lost. For Natasha it was denying that any of the kidnappings had happened. But it was Bruce who was really in denial.
Bruce held his denial that sweet little Steve would ever bring out the Hulk.
115. No
Steve loathed the word "no". It was not a hard word to understand, but it usually contradicted his requests, which he hated. It drove him crazy to know that Mommy and Daddy would say no.
But, he had other people to say yes.
Uncle Tony, Uncle Clint, and Uncle Thor never said no to what he asked for. That's why, whenever Natasha refused to give him ice cream, he'd go right to Uncle Tony.
After all, who was Tony to tell him no?
