Have you ever forgotten to zip your schoolbag?
Many times when i was walking on the campus, i saw some students walking with an open schoolbag,which looks like a huge mouth...well that's really awkward, lol
Sometimes I go forward and tell him/her :"hey, you forget to seal your bag~",
though it's none of my business...
Actually such mistake never happened to me, am I too cautious? heheh
I'm wondering why they made such mistakes?...
Yeah, it's a wierd question...lol
