No excuse required. The character continues to operate as it always has, run by those players who are present. This is made clear to all up front: miss a session if you like; if you pass along any instructions they'll be followed when and if they make in-game sense, but your character is otherwise at the mercy of those who show up. And the DM isn't going to change a thing.

Unless a player says it's OK for Bob or Sally or any particular player, even the DM to run their character, I never let my other players run the character of the missing player. I would hate to come back to a game to find that something happened while I was away and my character is irrevocably changed or damaged or played in a manner horribly against what I would have done.
I do think it's important to trust at least your DM well enough that they might run it, or your best friend in the group, but outside of situations where everyone in the group is my friend, I'd never let a group have control of my character.
That...and I usually take my sheet home every night. Kinda hard to run a character whose stats you can't see.
