Enouragement from a Friend

After my grocery shopping yesterday I came out to my car and found a note on my windshield. I actually did'nt notice it until I was driving, so I had to wait until I stopped at a red light before I could get it. You would'nt believe all the thoughts running through my head until I was able to read the note. I kept thinking, "I know I did'nt park illegally, did I? I hope I did'nt offend someone while trying to park." When I was able to read it it said, "Get those deals girfriend! :) Guess who!"

I have an idea who did this and if it is her she will know what this sign means.

For those of you who do not know sign language this sign means "I love you"

Thank you mystery friend for the words of encouragement.
