I had sent save the dates out to a few coworkers months ago. However one of the coworkers I had sent a STD to announced she was leaving the company. We are a relatively small company under 100 people. She invited a bunch of girls some of which have only been employed here for a few months out for a night on the town for her going away party and didn't include me. Is it wrong of me not to send her an invitation after she decided to not include me in her going away party? I probably won't see her that often after her last day but don't want to come off as being immature.
