"O.S." is the abbreviation that my husband and I have given to the term “old shit,” or otherwise known as “old stuff” if small ears are listening. This term has been used in our relationship for quite a long time. It is used to firmly remind each other that when arguing that we can not keep drudging up past transgressions that have already been resolved into our current discussion.
We have a rule that you can bring up a relevant past event only ONCE in a future argument…then it officially becomes “O.S.” and must be taken out of your argument arsenal. With four small kids around, we rarely have the time to finish complete sentences, much less beat a topic to death. We have to get to the point and resolve it quickly. We have found that when someone throws out the “O.S. card,” it adds quite a bit of levity to the situation and helps keep us on track. Give it a try and let me know what you think.
