Scrooge regrets many things after his visit with the Ghost of Christmas Past. Name two regrets.

The Ghost of Christmas Past showed Scrooge scenes from his early life.  He reflected upon two scenes with regret.  The first one was when he observed Mr. Fezziwig's Christmas party.  Mr. Fezziwig was Scrooge's boss when he was a young man.  Scrooge noted that Mr. Fezziwig was a kind and happy man.  His boss was encouraging to his employees.  Scrooge then became quiet.  The spirit asked Scrooge what was wrong.  Scrooge implied that he would like to speak a word of kindness to his clerk, Bob Cratchit.  He reflected upon what an encouraging boss Mr. Fezziwig was to him and regretted how he treated Bob.  

Scooge's other great regret was losing his sweetheart, Belle.  They had planned to marry, but Scrooge had become a greedy man.  He cared more about gaining wealth than anything else.  Belle told Scrooge that because he cared more for money than she believed he did for her, she would release him from their relationship.  Then Scrooge saw Belle speaking to her husband about him years later.  Scrooge could barely stand this scene because he was full of regret.
