We've found out that practicing cartwheels, making "landscapes" out of mashed potatoes and spinach, and the song Scarborough Fair are relevant --> is the connection the one of doing impossible things?
No Have you done such landscapes?
Yes Had someone else?
Irrel If so as a child?
I used to make them as a child and I recently made one With food on the dish?
Yes relevant?
Not really Is love relevant? Personal relationships?
No to these Is the song relevant for its text or as a song per se?
As a song per se, but explore I mean: is it relevant because it remembers something to you? Because it was the song of your wedding? Because someone used to sing it?
No to these Because it was the first song you learned to play?
No, but OTRT Someone sang it to you? Because it was released in a relevant year? Or maybe you sang it? You sang it to take the time? To perform the cartwheel (e.g. tempo or something along this lines)? (relevance as a song per se) or because something similar happened to you? e.g. in theater? or maybe someone asked you to do impossible things for the sake of love? Or you asked someone? (relevance for its lyrics/words)
No to allParsley, sage, rosemary and thyme relevant? Rosemary = remember me? Rosemary = a name? The girl's name? Is it connected to spinach somehow? Or the clue was only for guessing Scarborough Fair?
It was just the clue, no further relevance"landscapes" out of mashed potatoes and spinach --> relevant which landscapes? specific ones?
Generic landscapes, irrelpracticing cartwheels --> did you manage to do cartwheels as a child?
Yes To do it now as an adult?
I'm working on it 
is falling relevant? Vitruvian man (strange question I know)? Do you teach to do cartwheels to someone else? Maybe to teach power of will? Relevant where did you practice cartwheels? Air the beach? On the sand? Competitions relevant? Music relevant?
No/irrel to restexact connection to me at different ages. --> is the connection something that persist in your life (i.e. that was always with you/not abandon you)?
No, quite the opposite! Or maybe something that appeared at different stages of your life from time to time?
This is more OTRTSince the other thing to guess is a girl's name, does this latter thing refer to your name? Does the name of the girl make the connection to you at different ages? Your daughter maybe? To be sure: the first name of the girl? The second name? Is she a real world girl? Someone connected to you? You? Maybe a composite name that remember all the three things found out?
FA, the girl's name was Rosemary and referred to the word rosemary in Scarborough Fair
