Do not invite us anymore!

Me and my boyfriend were invited home to a relative of his so we decided to buy some pizzas to surprise them with but the surprise was on us. We arrived at their house and it was all dark and no one answered the door. We waited with our warm pizzas outside in the dark sitting down on their doorsteps. The agreed time was 20:00, but no one arrived, so when we had waited 20 minutes we thought maybe something had happened or maybe they forgot, so we sat down and ate up all the pizzas and left the pizza boxes and bread crusts on their doorsteps. The next day we met the relatives and it was obvious that they told us a lie of why they were not at home...
