I have learned to stretch my patience by a mile in order for me not to bludgeon those who irk me. There's a certain person in my life who has such a foul mouth that it wouldn't shock me if she gets slapped one day. That will teach her a lesson. She has the ability to answer back, devoid of qualms about her attitude problem. Your family can only hack your attitude to an extent and still love you despite of your lousy behavior but once you step foot into the social scene, you'll be fending for yourself. Fix it and swallow the harsh reality because whether you like it or not, you're bound to deal with others.
Some people just never learn. Pull your crap together! TSK TSK TSK!
