Nope. But then again I only went to one that would qualify as such. Instead, it was a trainwreck of etiquette don'ts:
-It was for the 3rd child.
-Hosted by the parents
-Same gender child as first 2, eldest only 4 years old so they had all they needed
-Presents were expected but baby already born
-Had to address own envelopes for TY cards.
(I would have skipped this entirely knowing all these facts (except for the last) but it was for a coworker when I was just out of law school and everyone else in the office (female) was going and I didn't want to look like a b*tch if I didn't attend, and at least for me I hadn't gone to the prior showers. Most of the other ladies there were actually at the earlier ones though, poor things.)
