There is a section of the Zemiros we say Leil Shabbos. It says “u’miyut avonos.”. Why would we ask Hashem for only a few aveiros instead of none? One answer is that it is technically assur to clap, dance and go to mikva on Shabbos. Sechita, whatever. But what kind of a Shabbos is it without clapping dancing and a hot mikva? It isn’t as geshmack. So we ask that the Aibishter forgive us these few.
