Cursavam estes dois moços a academia de S. Paulo, estando
|
|
Luís Alves no quarto ano e Estêvão no terceiro.
|
|
Conheceram-se na academia, e ficaram amigos íntimos, tanto
|
|
quanto podiam sê-lo dois espíritos diferentes, ou talvez por
|
|
isso mesmo que o eram. Estêvão, dotado de extrema
|
|
sensibilidade, e não menor fraqueza de ânimo, afetuoso e
|
|
bom, não daquela bondade varonil, que é apanágio de uma alma
|
|
forte, mas dessa outra bondade mole e de cera, que vai à
|
|
mercê de todas as circunstâncias, tinha, além de tudo isso,
|
|
o infortúnio de trazer ainda sobre o nariz os óculos
|
|
cor-de-rosa de suas virginais ilusões. Luís Alves via bem
|
|
com os olhos da cara. Não era mau rapaz, mas tinha o seu
|
|
grão de egoísmo, e se não era incapaz de afeições, sabia
|
|
regê-las, moderá-las, e sobretudo guiá-las ao seu próprio
|
|
interesse. Entre estes dois homens travara-se amizade
|
|
íntima, nascida para um na simpatia, para outro no costume.
|
|
Eram eles os naturais confidentes um do outro, com a
|
|
diferença que Luís Alves dava menos do que recebia, e, ainda
|
|
assim, nem tudo o que dava exprimia grande confiança.
