Cursavam estes dois mo<6D>os a academia de S. Paulo, estando
|
||
Lu<4C>s Alves no quarto ano e Est<73>v<EFBFBD>o no terceiro.
|
||
Conheceram-se na academia, e ficaram amigos <20>ntimos, tanto
|
||
quanto podiam s<>-lo dois esp<73>ritos diferentes, ou talvez por
|
||
isso mesmo que o eram. Est<73>v<EFBFBD>o, dotado de extrema
|
||
sensibilidade, e n<>o menor fraqueza de <20>nimo, afetuoso e
|
||
bom, n<>o daquela bondade varonil, que <20> apan<61>gio de uma alma
|
||
forte, mas dessa outra bondade mole e de cera, que vai <20>
|
||
merc<72> de todas as circunst<73>ncias, tinha, al<61>m de tudo isso,
|
||
o infort<72>nio de trazer ainda sobre o nariz os <20>culos
|
||
cor-de-rosa de suas virginais ilus<75>es. Lu<4C>s Alves via bem
|
||
com os olhos da cara. N<>o era mau rapaz, mas tinha o seu
|
||
gr<67>o de ego<67>smo, e se n<>o era incapaz de afei<65><69>es, sabia
|
||
reg<65>-las, moder<65>-las, e sobretudo gui<75>-las ao seu pr<70>prio
|
||
interesse. Entre estes dois homens travara-se amizade
|
||
<20>ntima, nascida para um na simpatia, para outro no costume.
|
||
Eram eles os naturais confidentes um do outro, com a
|
||
diferen<65>a que Lu<4C>s Alves dava menos do que recebia, e, ainda
|
||
assim, nem tudo o que dava exprimia grande confian<61>a.
