                                        " the lost bag "
I've lost my school bag. the features of my school bag are it is in the florescent color with all the light blue piping all over it corners. please if one found out my school bag then hand it over to me I'm a student of class 5-A ( use your class and section instead of mine ). It would really be helpful if you can find out my school bag.
