The church would be standing room only. And mum would be all annoyed and go “tfft, why don’t they come the rest of the year”. And baby me would think “fucking fake Catholics”.
Also remembering the time my 9 year old brother got drunk on eggnog and shout-whispered “WOW I’M SO DRUNK” to me in church.
My mum is still judging you if you don’t go to church, btw.
Honestly I’m pretty sure that, at least where I live, there aren’t a huge number more people going to Mass on Christmas and Easter. The Church just fills up tremendously because in most Sundays, a good chunk of people go to nearby chapels instead of the main parish, but on Christmas and Easter only the parish is open. When I go to the chapels instead of the parish there’s usually a good 60 ish people attending Mass per chapel; multiply that by 5 to 7 chapels and distribute it across the 3 Masses that are celebrated for those days and you don’t really need to have those many more churchgoers than usual to fill up a Church.
YMMV though, I live somewhere that religion isn’t necessarily as tied into identity as the US, I think in the US if being Catholic is part of your identity but you cba going to Mass every Sunday you have to still validate your identity by going twice a year. Over here it’s really just whatever. Maybe the identity thing is just an impression I get from online American tradcath types though.
