My husband taught for 38+ years in a high school. The last few weeks were a nightmare with finals, last minute papers, grades and of course the seniors who crapped out the last semester and were desperately looking for ways to make up missing grades so they wouldn't lose their scholarship or college admission eligibility He'd leave school on the last day then go back about two weeks later to clean up his room and turn in his keys.
Funny, but his blood pressure has been so-o-o-o much better since he retired.
Have a wonderful summer...you deserve the rest!!
