No big deal!

Ready to leave office around 8 pm,
by the time I passed by the restrooms,
considering none of the colleagues should be there,
I helped the security guard to turn off all the lights of the restrooms,
as usual as the other nights,
to save energy and electricity expenses.
However,
Only few minutes later,
my colleague suddentally stopped by my office,
and asked if I turned off  the lights,
as he was inside the male restroom,
I felt bad,
but he kept on saying,
"It is not a big deal!"

Lesson learned today:
Let the security guy do his job!
