We all have been in a situation where we assume for the worst, or just plainly made an inference, and then a judgement and then acted off of it. Sometimes these assumptions are correct, but there are moments when they are not correct.
We as humans are built to make assumptions because of dangerous situations and ensuring that we don't get hurt. But we need to take the time in situations to analyze more. We need to start giving people the benefit of the doubt and work harder to make sure we aren't hurting someones feelings.
Instead of jumping to conclusions and getting upset about how someone may or may not have offended you, put the other person first instead of yourself. We are always so consumed about what we need, and what we want that we loose track of how others feel.
So instead take a deep breath, and care about other people more than yourself. Stop jumping to conclusions. Give people the benefit of the doubt.
