A new pet peeve...

....people who are late to Mass. I've started going to Mass again and I've developed a new pet peeve as a result. Getting there as the priest is headed down the aisle is not so bad - but 15 minutes into Mass? As they are finishing the first reading? Bad. Worse? 30 minutes into the Mass as the priest is starting the consecration! Why bother at that point? Just receiving Communion doesn't do it. Showing up that late is inconsiderate and disruptive - not to mention that you missed the readings which is one of the most important parts of the service.
