You Are Welcome
Rashi cites the Talmud that the sin of the Golden Calf will plague us for all generations. The gravity of their iniquity was such that a deeply engrained flaw had penetrated into their construal. Although we had so passionately stated that we were primed and ready to accept the Torah without even knowing the details, shortly afterwards we seemingly dissented and displayed a lack of trust in Hashem. Even though we were under duress, having apparently lost our cherished leader, nonetheless, we failed to live up to our expectations. And that was forgiven but not forgotten!
