This was sooo cute I just love it.

This so sweet~ Even in a short amount of words you described a brotherly relationship perfectly! XD If I were sick and my parents saw me, they'd drag me out of bed and make me go to school anyways! 8D Lit' Cal scares me a little bit sometimes, but paring the striders together is just so awesome~ I think you did a good job and if your objective of the story was to make the reader go "Awwwwww~" You did an excellent job! If you ever do more Homestuck stories, I'll be sure to read them!

This was very cute!

However, there seemed to be a bit of a lack of punctuation and grammatical errors. Additionally, you really didn't seem to make much of an effort to add in detail. For example, here you wrote:

' "No you seriously don't look good are you feeling okay?" He asked reaching out and putting his hand on his little brothers looked paler then usual but his cheeks were red.

"Now that you metion it I don't feel all that great." Dave said floping back down on the bed.

"Okay no school for you today. I guess i'll have to call in for work too." Dirk started to get up but Dave stoped him. '

Now, nothing here is outwardly 'badly written' by any means, but there is a lot of room for improvement. I'm going to rewrite what you wrote here, in my own words, if that's alright?

' "No, I'm being serious," He asked, reaching a hand out to touch his forehead. "Are you feeling okay?"

Dave hesitated.

"You can tell me."

"Now that you mention it," Dave murmured, clearing his throat, "I don't feel all that great."

"I had a feeling. Well, no school for you today, kid. I'll call in for work too." Dirk started to get up, but Dave's hand reached out in a feeble attempt to stop him. '

See? Adding detail, proper punctuation, and good grammar really makes a difference in your story.

I remember my first time writing sickfics, and they looked a lot like yours! But with practice and paying attention to constructive criticism, you'll get there!

Good luck uvu
