[So accommodating! But a little worrisome as well... but that was for another day. Maybe.]
I thought so, but, well, maybe it would be nice if Ritsuka had a nice little stockpile of memories he could look at and share with you when he returns? And you could make it into a scrapbook! [smiles at the idea of Soubi cutting out dainty little paper-chain animals and gluing them into a book just for the two of them to share.]
Of course, you might prefer painting to taking photographs but those would probably be harder to store... [and fewer memories, but then again, there was more effort in a painting]
