Algebra

This is a photo that represents my day straight forward. I spent more time watching my TI than using it. 
I didn't go to school this week and haven't missed it even a tiny bit. Returning tomorrow for a choir practise makes me itch (even though I love the choir). 

Does anyone know why Blipfoto replaces my older photos with low quality versions? I capture them all with a camera (and upload in high quality) but  some of them were replaced after a few days. I went back and re-uploaded them but if this will keep going, I have to reconsider using Blipfoto for my future uploads.
