My Pulse is Rushing, My Head is Reeling

For the most part, there is a wonderful Spirit here on campus that fills me with peace.
There have been moments, though, that have made my heart race in the past month.

• Praying in Class - Oh my heavens. I volunteered to give the opening prayer in my English class and, upon sitting down, my heart was pounding. I've been part of the church for over 18 years - shouldn't I be used to public prayer by now?
• Bikes on Campus - There are sign all over stating that "bike speed is walking speed". I don't know if cyclists are going a tad fast or if I have sorely underestimated the ability of speed walkers today. Either way, it has taken great control on my part to maintain any kind of movement when they whiz past me; I fear for my well-being just a little.
• Speaking in Class - Again, this shouldn't be a big deal, but it takes all my reserves of strength to get my blood pressure back to normal after being called on to speak.
• The Bearded Repairman - The first time he had to come to our apartment, I was alone in the house and he'd come to fix a sink that I had no idea there was a problem with. I was sure it was all just a ruse to catch unsuspecting, defenseless females unawares - I mean, no one has facial hair at BYU-I, so he's got to be sketchy, right? - and I was planning my escape route when he left just as peaceably as he'd come.
  
• Leading the Music in Church - I got a new calling. And it's the same one that I had in Highlands. For some reason, though, I had some sort of stage fright about it, today, being so flustered I even ended the hymn and sat down before completing the fourth verse of The Spirit of God.
• The Fire Alarm During Relief Society - Okay, really only the initial noise was frightening, because I happened to be sitting right underneath the fire bell. But the alarm was actually semi-legit; we were all told to go home before the third block had even started.

Just some points of mild note - gotta love the moments of excitement that intersperse all the calm of homework and studying!
