I've just wanted to read that to my pet, but there's no option. Has this never been readable?

maybe you have to open it first before you can read it? Is there an option to open it?

Hopefully someone will post that knows for sure, I can't remember what I did with mine, sorry xD

No, there is no option to open it. Also someone could have told us in time, that all the invitations would no longer have the option to open them, once the event was over. I thought I had plenty to read for my pets and stored them unopened.

I don't think the unopened letter was ever readable, since it was evidence. The invitations are different, though, and should still be able to be read.

the opened invitations and hastily written notes are indeed still readable, however, you cannot open the invitations anymore to turn them into opened invitations and notes.

I believe Taikishime is right actually, that item was never readable. I have checked on SubetaLodge and I have not read it to my pet.

It doesn't have it listed as being a readable item at all.

o.k., thanks guys! Just bad luck, I guess.
