If he care you at any type come before you where ever you go but this found in bad boy also take a time if he come daily like 3- 4months not stop you in between market in front of your parents I'm saying you aa this of my experience I'm also of your age a boy come after me cantu imagine 2yrs r going2 complete he still come he purpose me but some problem I not commit him but he still love me and care me
I can't underestand about aboy he sit near me but sites by back of his body he has a lot shy and he is secret person
Does the boy look you in the eyes, is he trying to make eye contact and in some way reach you. Has he shown any signs of interest. These are all things you should look for. Perhaps, try speaking to him. You will be able to tell,if he is shy, he may just look away, but you will be able to tell by the expression on his face. Watch for body language as well, if he moves away fast, and looks away, not a good sign.
You are 16 stick with school don't worry about the boy
