Etiquette

[Nirvana]

So they messed up. The women were certainly invited, not their husbands.

How is this clear to you? My brother in law's first name is Celestino my sister does not have a name even close to that. Someone took the time to write that name on an invitation. My BIL SXXX is dead why send a dead man an invite? I don't know if any other men are invited. Its hard not to be offended by this and even further since I sent an email 2x and got no response.
My sisters are upset by this... understandably...at least to me.
