What is this power?

Okay girls have you ever had the experience of boys being able to get you to do something that your never would have considered before? It is the most annoying thing ever.

At my university, there is this mountain that over looks the university with a letter on it, symbolizing our school. It's a western thing. I don't quite understand it, but it is amazing to look at on certain days. Anyways, there is this trail that leads up to it that you can hike and overlook campus and the rest of the city. 

This last Thursday, I guess my roommates got asked to go hike it Friday night with a bunch of other kids from our church group. I had no idea about it until that night when I got a text from the roommate that was really considering it asking if I was going. I just replied I have no idea what you're talking about. My other roommate and I had kind of a long day leading up to it, and we were both tired (from differing health conditions. Mine was my head injury that is still not wanting me to have fun in college). The three of us went over to our best guy friend's dorm to watch a movie. The roommate considering the night hike decided to call the kid organizing it to see who was going. She was enticed by a boy she had just discovered was really awesome. My other roommate and I just kind of laughed at her and started to watch the movie without her. 

Not two minutes later, I got a text message from the boy I am interested in saying him and his roommates were going on the hike too and invited me and my roommates to come. I, of course, was then very torn. I decided to go. Complaining to my roommates that I hated boys the whole time leading up to the hike. (This is of course sarcasm. I was just frustrated that I got enticed into a hike when I should have been resting just because the right guy asked)

Of course I enjoyed the hike and I am so happy that I went. It helps when you have really awesome motivation. After the hike, my roommate, the boy and his roommates and I took a late night Mickey D's run. On the way back my roommate asked how when she asked, I said no but when he asked I went.

I proceeded to answer after we had said good-bye to them by saying what is more enticing: your roommate or the boy you're interested in. 

Really it's not that difficult of a choice. But why do that have to hold so much power??
