<human>: I have a co-worker and friend who is a young homosexual male. His name is Samuel but I, being immature, thought it would be be funny to save him in my phone as Samantha. No one knew this but me, it was one of those things that makes me lqtms.

He ended up calling me over a major network failure at around 3AM. I didn't hear the call but my sweet, dear, Fiancee woke me up rather abruptly and demanded to know who Samantha was and why "she" was calling me so late at night. I swore up and down I didn't know any girls named Samantha and then she told me to look at my phone. I had a hearty laugh and called "Sam" back on speaker phone to smooth things over with the missus. 

Lesson Learned.

Can you provide a brief overview of the text?
