Mijn vrouw ging naar het strand en kwam terug met een slechte geur van zonnebrandcrème op haar gezicht

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?
