Many, maybe most will not have reach you twenties yet, but I have written a little bit, and given you some photos of what life was like for me, my mother, my uncle and my father in our twenties. All of us lived during different time periods so of course life was very different for everyone. I hope I have conveyed this to you.
1 - Severina Snape was born in 1958 (top left photo)
2 - Severus Snape was born in 1960 (top right photo)
3 - Tom Marvolo Riddle was born in 1926 (bottom left photo)
4 - Louisa Snape-Riddle was born in 1978 (bottom right photo)
When I wrote this I was able to see strange coincidences that I perhaps have never appreciated before.
