I'm in the midst of wedding planning and would like to hear your experiences, as I have only been to one wedding.

I'm curious about if you've picked up on any unique considerations that went into the structural/event design as well as the emotional takeaway from attending the event:

What made that wedding distinct from the others?
What aspects of the wedding did you find thoughtful and memorable?
How did that wedding make you feel as a guest?
How do you want to feel as a guest at a wedding?

I’m writing the best man speech for my brother’s upcoming wedding. I haven’t been to many weddings so to be honest I’m not super familiar with the format of this speeches, or things I should be sure to mention (I.e. things like “be sure to thank xyz person”). I’m asking some family members but thought I should cast a wider net and ask here too. Any advice for writing this type of thing? Any memorable ones, good or bad, to emulate or avoid?
