"In my day..."

Hello this blog of mine is for writing and I am going to be writing a whole bunch of stuff! Well my prompt for today is "in my day..." so "In my day" why would you say that I mean cause it makes you sound old even if your actually not like if you are twelve years old and said "In my day..."! that would be weird, their only 12! one time when I was seven I was talking to a five year old about buying an I-phone and the little kid said "Well back in my day..." I was amazed that a five year old told me "In my day..."!
