So, Orsino, one of two things is happening to you. Either:
1) Your close friend and trusted consultant Cesario is actually a beautiful and cunning woman from a distant land, searching for news of her deceased brother whilst struggling to hide her feelings for you, OR
2) Your gay best friend has a crush on you.
You must act carefully at this point; any thoughtless caress, any excess in compliments, could fuel the fires of Viola's/Cesario's/Sebastian's unrequited love. And while the last thing you want to do is lead a homosexual on, it would be rude to simply dismiss your closest friend and ally. You must now tread the narrow path between misconstrued compliments and cold indifference. You must attempt what is seemingly impossible; you must keep your best friend while denying him what he wants more than anything. Because in all truth, there is almost no chance that he will turn into a beautiful maiden in the final act.
I am in a weird mood tonight (surprise!) but I can't stop thinking about 12th Night.
To me, it just seems like the ultimate pipe dream for anyone who has ever had a crush. It is the desire that, in the end, you are everything your crush wants, if only you are brave enough to be open with them. It is a cruelly unrealistic desire.
I don't even know why I'm stuck on this idea. I haven't had a proper crush in over a year, so it's not like this is reflective of my life as of now.
