Stop acting childish

To whom it may concern: You are older then me, yet you behave like a kid. Your childish behaviour pissed me off totally. I keep quiet and tolerant you and your action all because i don't wish to be as childish as you. I don't disturb you, so please don't disturb me. You don't like me i cannot force you to like me, vice-versa.
Bad mouthing other people doesn't make you a better person, please wake up your mind and mind your own business.
Stop all your jealousy and reflect on yourself!
