 We say that fields on $X\sgl$ in the image of the gluing map
 are transverse to $Y$ or splittable along $Y$.
 \item Gluing with corners.
-Let $\bd X = Y \cup Y \cup W$, where the two copies of $Y$ and 
-$W$ might intersect along their boundaries. \todo{Really? I thought we wanted the boundaries of the two copies of Y to be disjoint}
+Let $\bd X = (Y \du Y) \cup W$, where the two copies of $Y$ 
+are disjoint from each other and $\bd(Y\du Y) = \bd W$.
 Let $X\sgl$ denote $X$ glued to itself along the two copies of $Y$
 (Figure \ref{fig:???}).
 Note that $\bd X\sgl = W\sgl$, where $W\sgl$ denotes $W$ glued to itself
