Why did she always expect some kind of 'gratitude'?
It irritated him. Every single time she did something elementary (fix the GR, make him dinner…) she expected him to utter those two words. 'Thank you'. It was enough to drive him into the side of a building in frustration.
Bulma Briefs was his own personal fly-in-the-ear. She was the reason for the creases in his forehead. And so help him, if his hair started graying from the stress she relented upon his royal back, she would be the dead reason for his annoyance.
"Vegeta! Could you take five minutes and come shovel food into your mouth?! I called you light-years ago!" He flinched, shaking his head in irritation. There it was again. That thing she did. Like she could order him around. How ridiculous. The prince of all Saiyans and this woman thought she could tell him what to do.
He hadn't realized that he wasn't paying attention, but did it matter? It wasn't as though he was an integral part of anything, after all. The woman could go on just fine stuffing her face without his presence. Though, it wasn't like she should. He was, after all, a prince, and—
"VEGETA!"
Damned be it all.
