Things that make you go...ERGH!

I know this is silly for me to gripe about...but it gets under my skin and I just wanted to vent about it without anyone telling me I need to quit complaining!
Here lately, Brooklyn has begun answering the phone. She is very polite and well mannered and it is really a blessing because there are many times (like when I am trying to get Grant to go to sleep or I'm in the shower or working or something) that it is a huge help. As a matter of fact...there isn't ever a time I don't want her to answer the phone. BUT....what bugs me is that I've told her over and over that if she is going to get it...to holler "I'll get it!" so I don't bother to get up. Probably 5 times in the past 24 hours the phone has rang, I have dropped whatever it was I was doing (including one time when I almost had Grant to sleep) and RAN to get the phone only to have her answer it seconds before I got there. ERGH! Then on the other hand....when I just KNOW she's going to answer it...she doesn't and the call ends up going to the answering machine. ERGH! I know it's trivial and not that big of a deal...but just now, I was in the bathroom, drying my hair (which is a process --you girls understand) and I heard the phone ringing. I turned off the dryer, threw down my brush, opened the door and started sprinting for the phone....but she beat me to it. If I'd have known she was going to answer it...I could have just continued on with my hair. Am I totally crazy for letting this bug me?
I just wish I could find a way for her to remember to holler that she's gonna answer it.
