We all take on different roles and aspects of our personalities in different situations... some of us to a greater degree than others. There might be work-you, family-you, guy-friends-you, girl-friends-you?
How many different people are you?
Do you surprise yourself with how differently you can act (flirty, grumpy, silly, argumentative)?
On one hand, I feel it's sometimes constraining that a subset of people expect to see certain parts of you ... to the point where they fail to see what you're really capable of. On the other hand, putting on a persona can also be liberating- exaggerating and projecting the traits you really want to take on. Where does pretending become real?
