Coming Back

Coming back, trying to learn writing again and to learn understanding things that I don't understand.

I didn't understand before, when a person is complaining about my solution and at the end he said "you can do whatever you choose, I don't care", it means he/she doesn't agree and means also I should not do that.
Instead, he's explaining to others that the solution that I give is not a solution and I should not do that.
Why can't just he say to me "no, it's a bad solution and don't do that" ?
I thought I made him clearly that it's only a proposal, it's not a final solution and therefore I ask his opinion first..
At the end it's communication problem. 

*Sigh*
Lessons learned:
People sometimes too busy complaining and demanding the best solution or their solution without thinking that other people maybe spending their time and effort to help them finding solution at the same time, they just don't see what others trying to do..
Second lesson, I should ask people to be more direct. I think I'm mentally ready to listen to people giving their direct opinion.
Third, be strong. Being a minority teaches me to stay strong.
