Abstract
A recollement describes one triangulated category $\mathrm{\mathsf{T}}$ as ``glued together'' from two others, $\mathrm{\mathsf{S}}$ and $\mathrm{\mathsf{U}}$. The definition is not symmetrical in $\mathrm{\mathsf{S}}$ and $\mathrm{\mathsf{U}}$, but this note shows how $\mathrm{\mathsf{S}}$ and $\mathrm{\mathsf{U}}$ can be interchanged when $\mathrm{\mathsf{T}}$ has a Serre functor.
