It's not really a scold -- god knows I've wasted a lot of stuff for the sake of fun projects, this just happens to be past the threshold for me. Not entirely sure why. I think it might be because thermal paper feels kinda yucky: it has weird chemicals in it, it fades super quickly, and cannot be recycled. I would probably feel slightly better doing this on regular paper, although like somebody suggested I would maybe limit it to a Sunday thing.
