My wedding shower was grueling - so many presents to open, it took forever. I did try to say nice things about everything, but then they would be shoving something else into my hands to open, and making sure they had the name right of who gave it to me, and I'm sure some things got overlooked. I barely got to glance at some things before they were passing them on.
I do remember one baby shower where the mom received a hand-crocheted set of little lace booties, and there was a pause as the room fell silent and then twenty women said "Awwww" in unison. That had to be a gratifying moment for the maker!
