Some time when you are staying in a foreign country without any one

u will feel lonely

and after u found some one to talk with him u will think that u finally found a friend to

hang out and share your sad and happy times with him

..................

then some day without any reason he or she will tell u to not call him again and that will

upset u and u will be again alone so can any one guess what wrong did he do to let that

person to leave him ?
