Why did Marcy not vote on the extension of tax breaks? Not even a yes or no

Marcy has an X next to her name on the extension of tax breaks vote, which means she did not vote. She either was out of the Capitol Hill (on a date with Micheal Moore?) or she chickened out and thought if I don't vote, people won't hold it against me.
