“He/She isn't my type.” Most of us have said it, but all of us have heard someone say it. People have preferences in all aspects of life, but one of the biggest mistakes a 20-something-year-old can make is pigeonholing themselves into a single “type” of person when dating. Now, it should be noted that I am using the word dating in the most casual sense. I refer to dating as in going out and having a good time, not dating as in moving in together and getting a dog.
