My sister had a baby last year and while she is spending maternity time with him she died her hair "universe" bluish. My nephew is over a year and she is applying for jobs. She was setting up an interview the other day and she said "I want to warn you my hair is blue for now but I will be dying it natural when I receive a placement- i just wanted to do something fun before I went back to work" and the lady on the phone laughed so hard and thanked her for letting her know.
Or the time my lip ring got stuck and i couldn't get it out before my interview.
There are things we all get judged by at first glance and we can use those things to help change others preconceived notions.
