Life's Little Lessons

As you can probably tell, I just experienced one of Life's little lessons.
I was going to check my grades on my laptop when there was a knock at the front door. My mom grabbed Ginger and shut her in a room for a brief moment so she could go see who was at the door. It was a friend of the family who was there to talk to my dad about some things.
After my mom let him in, I was told to take Ginger into my room with me, since I was already headed there. (I had to take her so she wouldn't annoy us with her barking at being cut off from everyone.) Well, she ended up annoying me with her whining. I tried to ignore her by getting on my laptop. Well, turns out, my laptop annoyed me, too. You know those times when you shut down an old, full-screen program and it causes the screen to inverse it colors and make the icons larger? Well, that's what happened. So, while I was having issues with getting my laptop screen back to normal, Ginger continued to whine. I constantly told her to stop, but she wouldn't. Eventually, I stepped outside my door and went to the kitchen where my mom was. I asked her if I could please let Ginger out of my room, but she wasn't sure if my dad and his friend would be coming back inside or not. So, instead of risking the possibility of them coming in and Ginger tearing the man's leg and jeans to shreds, she said Ginger had to stay in there a little longer.
Annoyed as I was, I vented to my mother of my recent problems (above) and she said she'd take Ginger to the sunroom. She argued that even if Ginger did bark, at least I wouldn't have to hear her. (That part made me feel really selfish...)
I went back to my room and stared at my laptop. I had turned it off, hoping that would fix it, but it didn't. Also, it was taking forever to run "Startup Settings..." And when I came back to my room, it was still on this screen.
I forced it to shut down and tried again. I had the same results and sighed. Then, I paused as I thought of something that could fix the display. I tried it out, and it worked! Shortly afterwards, my computer finished running startup settings. I was so happy! Even if it was a small victory, it meant I didn't have to go to the HelpDesk at our school (which I am thankful that I haven't had to go).
I looked up and thought, "You know? I would've solved this earlier if I had just calmed down."

And it hit me. What I just experienced was one of those Life lessons that people are always referring to.
I felt like an idiot, and also a genius for just realizing this.
Relieved of my anger, I brought Ginger back to my room and found I felt much better.
