Hey Ana! Here are a couple of notes for you:

Remember to start a sentence with a capital letter.

You've used an accent ´ instead of an apostrophe '. This isn't a problem in terms of reading what you've written, but sometimes when you use an accent, the computer will format the text incorrectly.

The way you've used "fair" in both of these sentences is correct and fits the context well.

Cuidate y buen día!
