I went out of town for a funeral and came home to a PIGSTY . They left to go on vacation and left the house in a state of such grossness that it stank of rotting meat and fruit and something dead . I cleaned it up and went to throw their laundry into her room , and i literally could NOT push her door open .
According to the above context, answer the following question.
Why could n't they push her door open ?


Her room was messy .
