What is the most helpful bit of knowledge you have learned from this sub?

I was just thinking about how much knowledge I have picked up from this sub just from passively perusing the discussions. It has made me feel so much more confident and informed in my decisions.My favorite bit of advice is probably that the cake cutting is a signal that it's ok to leave. I have not seen this anywhere else. It's also interesting to hear about the different regional and cultural traditions.What is the most helpful thing you have learned here?! via /r/weddingplanning http://ift.tt/2vldSx0
