If done tactfully, no one's feelings will be hurt. Priests have to talk in front of a lot of people and try not to mess up. Talking in front of large groups of people can be hard for anybody. Just as anything else, with practice it becomes less difficult. That does not always mean every priest will be interesting every time he gives a homily.
Priests have no free time to do what they want.
Priests are certainly encouraged to take days off and take vacations in order to enjoy doing the things they like. Time for recreation becomes more important as schedules become more hectic. It is important for a priest to have leisure time and recreation is part of leading a fulfilled and healthy life. Lots of priests enjoy sports, going to the movies or the theatre, spending time with family, priest friends and other friends as well as a lot of other activities. Priests always have a meeting or mass or something else.
