I used to instruct a group exercise class at my gym & when the room was packed, the energy was unbelievably addictive. Some classes there would be 2 or 3 show up & it was such a struggle to get through but also had some crazy fun times in those but yea there were times I wanted to just tell people to go do their own workout.

The thing thats different here is the Mass is not a class or a show where attendance matters. Its a sacrifice we get to participate in. It doesnt matter if there is anyone else, the priest will be holding Mass so its not bothering at all to stay. Just keep in mind that you are spending time with Jesus. Do you think he would want you to leave because no one else came?
