Q: Text: a minor tifu, happened 14 hours ago.

i am a middle aged dude. i was staying in a hotel for work (i work as a financial controller in an it company). the previous evening i packed my bag with what i thought was a tube of toothpaste.

in the hotel before going to sleep (right after you know... i was alone in my room with nothing much to do with a laptop and free hotel wifi) i get the tube and put the white cream on my toothbrush. so far so good, i put the brush in my mouth and start scrubbing. i taste the "toothpaste" because something is off. i look at the tube and see it is sunscreen -_-

the next morning i told my wife and she got a good laugh out of it.
A: 
i brushed my teeth with sunscreen.
