clean up!

last saturday, i went to masato's house to help clean up his room, with joo mi.
masato moved his house before, but during the weekdays, he couldn't clean up enough, so he ask to us.
when i saw his room first time, i said,
"impossible!!!"
i really thought so.
we cleaned up for three hours.
i think we did very well.
after that, masato cooked japanese food for us, so we had a dinner together.
i enjoyed it.
but!!!!
next morning, when i get up.....
my sholder was hurting, i had sore muscle.
i think.... i'm getting older...>_<
