although that probably sounds insane to you at this time.
Went thru that, (or similar), with 7 grandkids. My youngest, unfortunately, is now 9 and beyond that.... but what he does now makes me think he's some kind of savant. He knows the lyrics to every song he's ever heard. He can listen ONE FRIGGIN' TIME and have the song memorized. I'm still working on the SpongeBob theme song.
I was in bed the other night watching a movie, I forget which one... and my 9yr old grandson was lying beside me playing Fortnight on his iPad... the movie had a sound track of many of the popular songs of today, or at least recently... I didn't know ANY of them... and while playing Fortnight he sang along with the lyrics to every song in that movie. I have no idea how he knows those songs.
Also this: Recently he was playing a YouTube and the lyrics were NOT ok.... the F word was coming up often BUT... bleeped out, but leaving nothing to the imagination... I told him it was 'inappropriate'.... he replied that it was 'ok' because F word was bleeped out, knowing full well what the F word being bleeped out was.
