Don't wear white, don't steal the spotlight from the couple, don't announce any major life events such as a baby or an engagement and don't rip shots with the open bar bartender. So, when a confused bride decided to consult the moral compass of the internet otherwise known as Reddit's "Am I the As*hole" about whether or not she should uninvite her own sister from her wedding because of a conflict in the past, people were quick to help deem a verdict.
Me (28) and my sister (32) have never really gotten along that well. My parents were divorced and so we never really spent much time together during our childhood. Once we got in our early twenties though that changed and we actually got pretty close. Both of us were in serious relationships and we would always talk about our dream weddings.
