I write thank you notes and hand them out to the specific teachers.
my target audience was my favourite school staff and it was to show thanks for all the academic help along the way of graduating through high school.
I placed the notes on the teachers desks in the early morning. all the teachers were happy about the notes.
it made me feel happy that I could brighten their days
yes, one of the teachers said they were having a rough morning and that my letter just made their day.
I would try to give more thank you notes to more teachers.
