I honestly am not too sure. Lukas sometimes borrows a few posts in place of the newspaper subscription he used to have which he gifted to the Urchins this past Christmas. So he takes our posts now in place of it to catch up on the recent drama. Reading seems to keeps him sane.
I'll head down to the old shop tomorrow and get them back.
Edit: I found them. Seems he made a paper wad for his cat to play with. Got them back a bit tattered.
