Tim’s had a horrible day so far: he barely got any sleep after a hard patrol, having almost dislocated his shoulder and getting nicked by a bullet on his side. Nothing a few stitches and an ice pack wouldn't fix, but Dick (who was in Gotham for the weekend) insisted on Tim staying the rest of the night at the Manor. Which wasn't the worst thing, but Tim couldn't fall asleep nonetheless. Then, after a wonderful breakfast from Alfred, he went back to his own house only to discover that his parents had come back from their dig a week earlier than planned.
They were not happy to see him coming back home around noon, when he was supposed to be in his room because it was the weekend. Thankfully, Tim's learned how to deal with them when they were mad over the years, and just waited for them to calm down. After a slap from his father and another lecture from his mother, they finally demanded he tell them why he wasn't home.
The reason why lying to his parents was so easy was because they didn't care enough to wait for an explanation.
That was also the problem, though - they didn't care.
He really shouldn't have been surprised when his mother forced him to change into his best suit that very same afternoon. After all, what would have been the reason for their earlier arrival if not another business opportunity? So with his injured side and still aching shoulder, Tim dutifully got ready for the gala, using some concealer to cover up the bruise that started forming on his face where his father slapped him, waiting for his parents so they could all go.
That's where everything started falling apart.
Because Bruce was there, too. And of course, if B was present, that also meant Dick. And to his utmost misery, {{user}} was here too. As Dick's plus one, no doubt, since the man absolutely loved dragging his friend into those events.
Now, Tim could lie to Bruce about why he was at the gala, freshly injured after patrol. He could even lie to Dick, but {{user}}? He couldn't. He wouldn't. Not in a million years.
