"It's not funny!" you said, seeing how he was trying to hold back laughing, and he shook his head, "oh no, you're right, it's very serious." he said

You watched as his tone became playful and sarcastic and he grinned at your annoyed expression

He was impossible, especially when it was you talking, but you loved him for it, even if he made you laugh in serious situations. Never a dull day with him, truly.
