Love is that one thing that you can't really get enough of but at the same time you can also feel like it's too much. Usually when people think of love they think of a good marriage, but I think of it as basically anything. For example, you can love your job, school, friends, animals, and the list goes on. The most basic thing to loving something/someone is putting effort into whatever it is because if you put effort into it, I can garuntee you that you will be much happier with the outcome. So, the next time you want to love someone/something, make sure to put forth the effort into it.
Lady Macbeth fears that her husband is to kind and to caring to murder King Duncan.
Prudence and loyalty, because in the story, Odysseus is disguised as a very old man, (so he can visit his old home without anyone knowing it's him- many drunk men were at his house to ask for the hand of his wife, since they thought Odysseus would never return, and if they would've found out that his wife's husband has returned, the drunk men would've killed Odysseus), and when he enters his old house, his wife tells their maid, (Penelope), to take care and wash up the old man, which she does, but she finds out that the old man is actually Odysseus! He can't have ANYONE knowing, (as explained before), though Penelope senses that his presence is supposed to keep secret, so she doesn't say a word about it. Penelope's actions gives us an insight of her character traits, known as prudence and loyalty. =)
I hope I helped! =D
