I don’t have synaesthesia, or at least I don’t think I do, but it has been in my life since the beginning ... before the external beginning, even ... since the womb. My mother was a synaesthete. She associated colour, numbers and sound (particularly pitch), so my joke now is that I couldn’t burp or fart at the dinner table without her telling me it was the number ten, a slightly murky orange and a B flat.
