Life comes with some unalterable certainties like the change of the seasons or knowing a Pizza Express will taste the same in every city in England.
If you want proof of how much people hate change, just look how upset people are about Big Ben not bonging for a little bit.
One thing we can always depend on however, is Emily Ratajkowski's penchant for a weekend sans clobber.
The 26-year-old model/actress and regular nudist took to the Gram this weekend to showcase her snapshot with the caption, 'Saturday morn'.
If you're feeling a little downbeat about your Saturday morn underwear ritual having seen this, don't worry, it's the taking part that counts.
The image is the second in a recent series of breakfast thong and crop-top shots soon to be showing at the Tate Modern (probably).
