Hi everyone~!! I tried to think about something new but to me, the biggest problem is still how to remember ppl's names:( So I come back with my idea at first and come up with new idea of how to clean a cell phone's screen. My two problems are: -I can't remember people's names well ( very very bad at it>"<) and many times, I want to know info about some famous people cauz when my friends talk about them, I have know idea and feel like a fool'_' -My cell phone's screen get dirty very easily and when I use something not a towel to clean it, I think why do I have to clean it like this? So this is my second problem of how to clean a cell phone screen well and conveniently. By the way, I made a rough ppt of the solution I can think about. Check it out so tmr I can explain my thoughts better^^
