ScenicViewer: It was the first year for me too. There is an older couple in the congregation, wife is a pioneer, that would always mail me an invitation, but not this year.
I have to take it back. Yesterday (4-20-17) I received the invitation from the usual couple, many days late, which was postmarked 4-6-17.
I guess there are two possibilities here, one being that the Post Office dropped the ball and delivered 14 days after the postmark even though the sender and I are in the same small town.
Second is that the couple have identified me on here, noticed my post, and sent the invitation late. The brother told me many years ago about how he backdated the postage machine in his office to send the IRS his tax return so it would appear to be on time even though it was actually late - it's the postmark date that counts with the IRS - so he definitely knows how to manipulate such things.
I don't know for sure what to think, but it was probably the Post Office dropping the ball. However if they know who I am on here it's a good thing because it means they are reading this site and are getting a good dose of the TTATT.
