While the mane six are depressed about being alone on Hearts and Hooves Day yesterday, a package is given to Twilight. Opening it carefully, she finds a beautiful necklace. But what is the occasion? Who gave it to her? Will she find out who it is?
(Proofread by my bestie, Justin!)
Hearts and Hooves Day does tend to mess with one's head.
This is kinda sweet, though your proofreader did miss a couple of howlers.
I suggest putting a space between every paragraph so it doesn't look so squished together. There are also some grammatical errors such as forgetting to capitalize the first word in a sentence, or putting a period at the end of somepony's dialogue when it calls for a comma. Other than those mistakes, this story was fairly good. Oh yeah, there are also some parts that could use semicolons instead of commas.
Heh, thank you two-- my friend isn't the best with grammar, because he's from china, and has bad english. However, he's the only person I know who enjoys ponies enough to even read a fanfic, so he was my only choice.
