Should you change your attitude so that everyone takes you seriously? Well, probably yes.. But why should you change who and what you are... Being nice, forgiving and kind was always your attitude..I agree people may have to change themselves so that people do not take them for granted... But it's like coming under the influence of someone...
P.s- Sona, whether you made a mistake by marrying Dev or not, you will always remember the strongest and most sensible character in the show..
