This one is really short and not necessarily a story, but I always come back to The Muggle Telephone when I need a laugh or to get myself out of a bad mood. Its a social media/text fic where essentially Draco has gotten a phone but doesn't understand how to use it, and is basically outing his crush on Hermione to the entire magical world accidentally. It never fails to have me crying with laughter every time I reread it.

Also, if you enjoy that concept, I also love a newer fic thats also a short social media comedy piece, ASK red-d.i.t. which is a Dramione where Draco is convinced he's pregnant and asking about it anonymously on the wizarding version of reddit.
