All days of the week are capitalized. Sunday, Monday, Tuesday, Wednesday, Thursday, Friday, and Saturday.
If you are asking if the word 'weekdays' is capitalized, then no, it's not. :)
Hope it helps you
I think that 'adamant' would be a good word to describe this behavior.
Adamant is a word that can be used to describe a stubborn person that is unwilling to be persuaded into a change of mind. This would be a good word because in the sentence, the subject is doing something that would be considered slightly extreme to the outsider for what he/she wants. From these actions, we can see that he/she is unwilling to change their mind until they achieve their goal, which in this case is moving the cat's crate to the house.
Yes they should learn other languages then English, it will help them communicate with people around the world using their languages
