My in-laws passed away over 20 years ago. They never much cared for me...too dark, not educated enough, didn't make any money, (although I was always employed) and any other thing they could find wrong. My inlaws used to send my prospective wife up to the store because they knew a guy she used to date worked there and he was all they wanted in a son-in-law. They even told me to my face they didn't like me. I was never disrespectful to them and usually stayed out of their way.

One day I decided to break up with my future wife and told her so. Through tears she asked me why. I told her well, your mother dosen't like me. My now wife told me I don't care if she likes you or not, I love you. That was over 35 years ago. The in-laws never did like me much but, I never showed any disrespect toward them ever.

as for spilling things.....I never yelled at the kids for it and I was never yelled at for it when I was a kid. Accidents happen.
