For most people, the universal one day that is celebrated that is not a holiday is birthdays. Birthdays can be stressful for some because it represents them getting older. Others celebrate their birthdays because they celebrate life and getting to add another notch in belt of life! lol
People celebrate birthdays differently as well, some have a gathering with friends and family, others go on trips to celebrate and others get a little tricky and throw 'surprise' parties.
This is always a mixed bag because you never know how the recipient will receive this! I.E. this teacher and how he responds to being surprised!
This teacher's actions was totally out of line! If my phone was broke after that he would have had to pay for it! I would have lost it!
The good news is that it actually turned out to be a well placed prank by a student and teachers and the two teachers on the class that was currently witnessing the craziness! They used an already broken phone because if the phone was not broken that is would be what you call "committing to the role"!
