Former Friends let me down

As part of the new category I want to start writing about, here's a situation I found myself in some time ago and I've struggled with moving past it, with minimal success.  I won't mention who Friend1, Friend2 and Friend3 are but I've got other aliases for them here.  Mostly I'm sharing this for posterity because someday Moose and Squirrel may find themselves in a similar situation.

Friend1 sent out an email to two mutual friends and myself.  Friend1 has access to box seats at a sporting event and we have a choice of dates but we need to jump on this pronto.  Friend2 writes back that either date is good for him.  I write back suggesting that the second date would work best for me. Now the fun begins. 

About 12 hours later Friend3 chimes in.  He responds to the email from Friend2 and suggests the first date because he will be out of town for the second date.  Friend1 says he'll check to see if that date is still available and asks if I can make it.  I check and cannot get that day off of work.  Somehow the date that worked for me was forgotten and Friend2 got to go to the event.  Did Friend3 not see my email?  Unknown.  Did Friend3 manipulate the situation so he could go?  also unknown.

Do Friend1 and Friend2 have the smallest penises in the world for pretending not to notice what Friend3 did?  Absolutely.  Either one of them could have simply replied to Friend3's email and said "hey what about what Icarus said regarding his availability?"  Instead they dropped back to watch and see how it would play out.
