Your nice story reminded me of an old anekdote that I've heard.
A man wants to go shit, he is in the toilet doing his best, sitting in silence, trying, but he can't. So he uses all his concentration and keeps trying.
After half an hour his wife passes by the toilet and sees the light. She turns the light of and hears a SCREAM: "Aaaaaaah!"
So she turns the light back on and asks: "What happened? Why are you screaming"
And the husband answers: "I thought my eyes exploded"
She didn't know he was there and decides to turn off the light
