A formal greeting to your instructor such as dear instructor ( last name)

Most instructors should be addressed as “Professor” or “Doctor” followed by their last name. Make sure to double check the spelling of their name before you hit send. Some professors have hundreds of students and may need some context to be able to place you and answer your question.

for me i have felt invisible when i was clearly struggling,or,i made a great achievement ,and,nobody took to notice me either because they just didn't see it,or,people just turned their back on me.i can see a person being invisible by choice,or,without choice like i did.the people who are invisible by choice don't try to talk to people,don't try to make friends,and,keep to themselves.i haven't been one of those people so i couldn't give you a reason.

hope this and can i get bainliest my dude : d
