For me it was Interior Decor school.
The attitude where fashion is all and terribly important and you must impress this upon your client and pretty much force them to buy into it (literally as well as figuratively) completely blew my tiny little mind.
No one liked to consider any other POV - they just would not condone it.
Now I am doing Production makeup and I was fully expecting this to be the same but I now recognise I am older than the others and am a good deal more mellow about things.
Also - I am in an industry that freely acknowledges it is about make-believe
And we are having a lot of fun with the tutors expectations.
