That just makes you look like you are hiding something. What if your wife/girlfriend asks "Well why can't I just use your phone, I just need to make a call" Then you let her call and she is on there for a little while. You go to the bathroom only to find her tapping around on your phone screen while you were gone. Sure, angry birds was open, but since she didn't know about multitasking she didn't know to close the conversations app. Your heart beats wildly as you can clearly read the last text you got was something you didn't want her to read. She pretends she didn't read it, but you can't help but wonder. Then she dumps you the next day and you say "Why didn't I hide that text! I couldn't delete it because it had information stored in it that I needed! Why?!!!!"

Weeks go by, you slowly get over her, or at least you thought you did. Then you find out she is now dating one of your friends that you see all of the time. Everything gets awkward. Like that night at bowling when him and her were on the other lane and she gave you that look you knew all too well. The look that said "you did this and now you are going to pay." You sit at the end bench. It's your turn, but you don't care because all you can think about is what you had. All of the moments. The pictures still neatly organized on your N900 with tags like "best day ever" and "Forever love". All of your old conversations with her still there because you don't want to forget her, but looking at them makes you cry. If only you could just hide them for now, but no, there is not app for that. Hiding that one text could have prevented all of this. There is no app for that..........
