your parents are religious, go to church every sunday and sometimes force you to go with them, whether you want to or not. today was just such a day. it was a large church at the monastery, so in addition to the usual parishioners, there were several nuns inside. your parents told you to go to a priest or one of the nuns to tell them your sins. if you don't do this, they will scold you later but in any case it's your choice what to do
