Input: Text: obligatory this didn't happen today, this happened a few years ago. 

i was being young and foolish, chasing my little brother around teasing him. we had been spending the day at my great grandfather's house and it has gotten late in the day. my parents were separated but my mother had phoned my dad to say goodnight to my little brother (she had my little brother, my dad had me), and my great uncle made the remark "aww you gotta phone your mommy". without thinking i wittily snapped back and said **"why don't you phone yours"**, and it had not hit me until a few hours later. six years before this my great grandmother (his mother) had died of liver cancer. i had accidentally told him to go die. a few years later he died of heart complications due to years of smoking.
