I was having a discussion with my friend from back home and he was going on about how he and his girlfriend go through each other's phone and FB on a regular basis. I thought this was strange. I do know the code to my GF's phone but I NEVER go on there unless she is asking me to read a text for her while she is driving or I am sending a pic she took to myself. The same goes for her. What do you guys think? Is this normal?
