I know, yes. I know how those things work in the algebraic setting, but it just extremely difficult for me to imagine the spaces or how the shape affects the homology or homotopy. Something as simple as [math]\pi_1 (\mathbb{R}P^2) \cong \mathbb{Z}/2\mathbb{Z}[/math] took me a day or two to visualise. It follows easily from the bundle, sure, but to see it instead of just writing some magick runes on paper. I hate topology and geometry.

Yes.
