We are currently at the parents of our husband, they live in a private sector. The neighbors had such a commotion from 5 pm onwards, mainly boys teenagers (14-16 years old as I understood). As it turned out, the boys were having farewells. One boy is leaving for some sports boarding school until New Year. They don't do such farewells like that. They stayed up all night straight, probably even now music is playing Do you think such farewells are normal?
