When I'm 21, I'll want to be 16?? I don't know....
No. I'm likely a rather ignorant teenager, though I tell myself otherwise.
I think this only applies to me with two or three years ago being the youngest I would ever want to be again. Today I certainly would not like to return to 14, but in two or three years, I could see wishing to be 16 or 17 again.
When I think I may be getting old, I recall all the hastle I passed through and I quickly feel better.
