Answer:
He did not get anything for my mom on Valentine's Day.
Explanation:
You don't capitalize mom or dad in a sentence because it is used as a common noun.
And you do capitalize Valentine's Day because it is the title of something, it is the title of a day. And there is an apostrophe because that is what it is officially. when you look up valentines day, you can see there is an apostrophe.
Therefore, the answer is, He did not get anything for my mom on Valentine's Day.
Hope this helps!
