THINK TWICE BEFORE PLAYING A PRANK
We all play pranks on other people either for fun or under peer pressure or some times to harass some one or in innocence but not with the intention to hurt some one. However at times pranks become deadly & it becomes an offense.

Dost ki yaad me
Dosto aaj aapko main apne Aligarh ke bare main batata hoon
WAH WAH Kanpur
Woh Center Point ki sham, woh Ganpat ke rasgulle,
Woh Numaaish ki ice cream, Wah tanga stand ki chaat.
Woh Khayali Ram ki mithai, woh Quality ka dosa,
Woh Mehak ki pav bhaji aur Sindh ka samosa.
Woh rikshaw ka saffer, woh Naqwi Park ki hawa,
Woh Gandhi Park ki raunak aur AMU ka sama.
Woh January ki kadake ki sardi, woh baarishon ke mahiney,
Woh garmi ki chuttiyan, jab chute te they paseeney.
Woh holi ki masti, woh doston ki toli,
Woh Curfew ka mahol, woh Ganga ki leheren,
