Hey, can you send me that picture?

A friend just asked me if I had a picture on my phone of an item, in order to show their grandma.  When asked, I responded 'nope don't have', because I assumed they were wanting me to send the picture from my phone to them at that moment. 

If I were to write this down in my journal and then someone (dubbed Person A) in the future came along and read it, they may say 'Oh look! Proof that he was lying and didn't want the other to see it!  He said that he didn't have the picture, but later on he emailed it to his friend, probably out of guilt for lying.  So he did have it!'
