117/365 Letters on the run

Most bottles of shampoo, specifically the printing on their labels, hold up impressively well in the shower. For some reason, the letters on this little bottle have decided they'd rather take up residence somewhere else.

It catches my eye all the time because I find it funny to see a solo, intact "y" sliding down the bottle or a "P" trying to blend in with the word "leaves" while the rest of their neighbors are staying put. Where do they think they're going?

I have a bigger bottle from this same brand whose letters seem to be content to remain where they are. So what makes this one different?
