Padmé would have wanted to come to the funeral, had she been able. However, she has another pressing engagement at the moment. Specifically, she's storming a Trade Federation battleship.
She knew from the start that her day wouldn't be normal, exactly. First they landed in the Gungan swamps, pleading with Boss Nass to send his troops against the battle droids, knowing all along that they wouldn't stand a chance. Then they stormed Theed, and captured Nute Gunray, which should have meant the end of the fighting, if not for the fact that his second-in-command really hated him, and also was looking for job opportunities. When the news came that the Gungans had lost quicker than expected, Padmé's advisors were already telling her to surrender.
Except that another piece of news came in, that a starfighter pilot had scored a hit on the Trade Federation battleship before being killed, and that for the ten seconds immediately afterwards, the battle droids had all frozen in place. It seems that the Federation was actually cheap enough to just not install operating systems in their droids, and they were all controlled by the central station. So Padmé had the bright idea of sending the ace pilots of the Jedi Order to capture the battleship, and just win by default.
Master Windu wasn't a fan of this. As he told Padmé, the Jedi have no authorization for offense. All they can do is protect and accompany Padmé and oh shit she can't be serious.
