We all have lived even once in our lives some embarrassing episode and we remember it as if it was yesterday, like you, I think one of the best things in life is to learn to laugh at ourselves to face those moments with less embarrassment, the truth is that laughing at those moments makes them more bearable.
What a blessing that the Lord delivered you, even without you noticing it, from that drip that had you so stressed and you were able to finish your sermon already restored! Greetings.
