I hated maths at school. I think this was because of truly awful teachers, the lack of romance and the accepted premise that it was difficult. I regret this now as some of my best friends are good at maths and clearly gain spiritual strength thereby.
Of sines, cosines and house signs, I understand only the latter.
From the extraordinary Okinawa Boot Sales I find Jennette who make signs from bits of wood and shells. I commission her to make a sign for my house that says Tigh na Mara.
Today after several false starts I pick up the sign. Jennette is a military wife or maybe she is a Marine and she exudes goodness. She charges me $5. I tell her she is nuts, but she is too good.
I take it home and hang it on my door. Now people will know the name of my house.
