Ma femme est allée à la plage et est revenue avec une mauvaise odeur de lotion bronzée sur le visage

I never thought it was strange and I didn't complain about my wife leaving the house to go alone to the beach, but this time, she came back a little later than usual and on top of that she came home with a very bad full that I imagine was suntan lotion on her face... for what else could be of bad smell on the face of my lovely and faithful wife?
