Not only was a child of the 70's but by the time 1979 I had Two nieces and a nephew, and I was 14 years old.
I'm not boasting or anythingm but that's what happened to me during the 70's when I was six years old I became an Uncle, and when I was 20 years old I had 7 nephews and neices, and now that I'm 37 years old I have three great nephews and 1 neice with another one on the way.
