I agree with the person above.
It should be - Tu hiciste mucho ayer.
This is the conjugation of the verb <em>hacer </em>in the preterite form:
hice, hiciste, hizo, hicimos, hicisteis, hicieron
Happy, because instead of being sad they are happy because they are close to those who were close to them that died and get to party and be with their spirits.
