Not Flushing The Toilet

We were not flushing the toilet after peeing. We tried to save water, so we basically peed until someone took a dump. Then one day, I went to a family friends’ house and freaked everyone out because I didn’t flush.
Edit 1: forgot to mention that we were a family of five with one working toilet, and my dad shits like three times a day.
Edit 2: Our bathroom was on the second floor, and it had a window.
