Sometimes the action buttons just disappear (bug), loading/saving or similar might help.
However, most of the time it is your needs which will prevent you from doing stuff. If you look at the top, you'll see the "0" next to the shower symbol - that means you stink. Well, Mike does at least. Go home, take a shower. Also, you will have to eat soon or be stuck again.
Hint, since this is a 9am picture: always (unless there are very good reasons not to) start the day with a shower and a meal. My usual setup is alarm at 6am, shower til 7, breakfast til 8. Once you're closer with the girls you can move this back an hour for the added benefit of common showering and eating with Bree, but at 6 the bathroom is always empty. At 8 you can already start working in the office (though nobody will be there except for possibly Shiori), alternatively you can play on the Zbox, once bought, to raise your happiness if it is an issue.
