I'll say you're ascribing nonexistent intention to my comment. "Trying" implies I have some goal in mind, sarcasm among people I'm close with is realistically the goal. That doesn't change the reality that on occasion it didn't give someone pause. It got my SO and I to seriously consider inventing a surname. Ultimately, my SO keeping her name was the right choice for her. Her reasons were different then yours, everyone will have different reasons. Most people assume we have the same last name at the end of the day. No one cares that we don't.
