If you're not a parent but plan to become one some day, take my advice and practice humility. You're going to need it.
For example if you live in a cold climate, your child might make an announcement that goes something like this ...
"Hey Mom, I just farted in my snowpants and now I'm all extra warm!"
... followed by hysterical laughter ... in the produce department of a grocery store ... with lots of people around.
