It's #LetSansRestDay, so here goes five happy Sans times.
-- It was the first night on the Surface. Sans stayed awake for hours just so he could see the night sky for the first time, despite being so tired after everything that happened Underground. It was raining, and he was a bit sad, so he let go a "c'mon can't you let little old me enjoy my freedom for once?" And suddenly, the rain stopped and all the clouds cleared out, showing him a wishing star on his first night. Sans eyes became litteral stars as he let himself fall on the ground, happier than he ever was for months.
-- The first time he realised Toriel is hilarious when she's drinking too much. It was just supposed to be a nice little sleepover with Frisk and her, but once the kid went sleeping, Toriel proposed him alcohol. Sans is quite resistant to it, but he soon discovered Toriel is not. At all. He laughs so hard that night there's a lot of time he got scared his jaw would dislocate. Toriel danced with him even if he was not touching the ground, she asked where were his hair hiding while inspecting his skull with concern, and she even convinced him to go see Papyrus at 3 am to sing Christmas Carols even if it was the middle of July. Eventually, Sans got hit with alcohol too and they spend the night putting quiches with a whoopee cushion surprise in the middle under every bench and trees at the park, giggling like idiots. It's one of his best memory.
-- After some months of therapy, Sans wanted to make a surprise for his brother. So he passed a engineering exam once again, and just let the diploma on the table. Papyrus could be heard screaming with excitement miles around the house. He crushed his brother in a hug saying he's so proud of him. Sans said he's proud of both of them too. They cried a lot that night, but it was happy tears. They celebrated the official end of their bullshit past, and they're celebrating it every year from now on, it's tradition.
-- The day Papyrus got married. The ceremony kept being interrupted by Sans loud sniffing as he's trying so hard to be a brave boy and not bursts in happy tears seeing his baby brother is a beautiful suit and happy like never before. That's clearly a huge big brother moment, and he feels like he did a good job raising Papyrus to be this cool. And the more he thinks of it, the more he wants to cry. He's so proud. Everyone thinks it's cute.
-- The first morning when he didn't have any nightmare. He felt so good and relaxed, he just layed down in the grass in the garden for hours, doing and thinking of nothing, just enjoying the nice heat and the sounds of nature. And Papyrus just let him. And even joined him at some point, to ask him while he didn't stop smiling since the beginning of the day. Sans just said he was happy to have him and everyone in his life and that he wished it never ends. Papyrus just hugged him and wished him the same.
