This is not a "flaw" of mine personally, but I think often about how what is a flaw from one person's perspective is a benefit from another's. One place I frequently see this pop up is language barriers for people in relationships whether romantic or professional. It would be easy to assume that if you have a poor grasp of a language, it would be a detriment, but many people who have done the hard work required to form a relationship with somebody where there is a language barrier will tell you, in fact, that the barrier is a blessing of sorts. Without the normal nuance of connotation, word choice, and assumptions, you instead are forced to discuss things very explicitly and clearly, much more so than you would in normal conversations. This strengthen's your relationship and understanding with that person. Topics which may be normally difficult to discuss or ask about explicitly become easy to do so because it's understood that you are asking because you legitimately do not know the answer due to the person's other culture or upbringing.
