Just Me And Nothing

One day... I woke up from my bed and I found an envelope at the foot of my bed I opened it but it was blank I was confused but uncertain I searched the envelope but I couldn't find anything not even an invitation nor a reminder I thought it meant something so I went outside I put it under the light so I could see well But it was still blank then I realized... there was no message at all only me searching for proof that someone cares
