The Life and Opinions of Tristram Shandy, Gentleman Book 1, Chapter 3 Summary

Tristram tells us to listen up, because he heard the story of his birth from his uncle, Mr. Toby Shandy.
Anyway, Tristram's father is none too happy about Mom's interruption. Anything Tristram does from here on out is blamed on this incident (poor Tristram), including playing with his toys incorrectly.
Tristram's mother doesn't understand how it could possibly matter. Smart woman.
(You're not alone: it's almost impossible to figure out what's going on here. Trust us, it'll become clear.)
