Why does torvald make such a decisive show of mailing the letter firing krogstad against nora’s pleas?

To show superiority and authority over Nora.

Explanation:

Nora, Torvald, and Krogstad are characters in the play "A Doll's House", by Henrik Ibsen. Torvald and Nora are husband and wife, and they a very sexist and abusive relationship. Torvald regards Nora as inferior, dependent, incapable. He sees himself as her lord and savior. To his mind, Nora must do everything to please him since, without him, she would be nothing. When Nora begs him not to fire Krogstad - who is blackmailing her -, Torvald gets upset. He will not let a woman tell him what to do, even if she is asking, like Nora is, in a submissive manner, promising to entertain him. He makes such a decisive show of mailing the letter firing Krogstad because he wants to make sure Nora knows her place. He wants to show his superiority and authority over his wife.

free time is when all my homework and chores have been done for the day and i am "free" to do things that i enjoy doing.

usually i spend time watching television. as my favorite tv shows come on at specific times, i make sure that i finish my homework and chores well before the shows. otherwise i will have to miss them. mostly i manage to watch the shows but sometimes extra homework or chores may cause me to miss a show or two, but it is rare. anyhow if i know that i am definitely not able to catch a show in time, i will just set the video recorder to tape the show sothe evening when the weather is fine, i sometimes go for a stroll around the neighborhood with my friends. this is the time when most the neighbors have come home from work or school. we say hello to those whom we know. they are mostly friendly people and they acknowledge our greetings. once in a while we come upon unfriendly neighbors but we just ignore them and carry on. that i can watch it later.
