Subject Line

Do you ever go to start an email and get the subject line and just freeze. I do it often. If I have a purpose other than just catching up or saying "hi" it is no problem. But if I just want to send an email to a friend and share something cool I am doomed to the subject line "hi."
From: myemail@hotmail
Subject: HI
or
Subject: hey
Sometimes I try to be creative and "fun" but I feel like I come off looking like a dork.
Subject: The red turtle flies at midnight.
Subject: The grass could be greener.
For now, I'm going to leave the subject line blank. I don't need the pressure.

My cell phone.

I want to throw my phone out the window. No I don't. It is my lifeline, but it connects me to the good AND the bad! I love it when my friends call, I HATE it when people who want money call. Can I have the phone learn to ignore and not even notify me when people I don't want to talk to call?
