How does Mr. Pignati treat John and Lorraine during their first visit?

John and
Lorraine's first visit
happens in chapter five after they have conned Mr. Pignati over the phone

into giving them money for a fake charity. They show up to collect the money from the
poor old
man and he treats them with kindness and respect. He also treats
them like adults by offering
them some homemade wine. This suggests that he
does not realize that they are teenagers. He then
engages in small talk about
his wife being in California, followed by explaining to them how he
memorizes
ten things at once through mental pictures. Once John reminds Lorraine that they
have
stayed too long chatting, she asks for the money. Mr. Pignati seems sad
for them to leave, which
suggests that he is very lonely and doesn't usually
have many visitors. In an effort to have
future visits, Mr. Pignati invites
the two kids to go with him to the zoo sometime. Just before
the kids leave,
Mr. Pignati also shows them his pig collection:

"The table had pis all over it. And the shelve had pigs all over them. There
were
pigs all over the place. It was ridiculous. I never saw so many pigs. .
. There were glass pigs
and clay pigs and marble pigs" (46).

Mr. Pignati is
so kind to John and Lorraine on
their first visit. Not only does he treat them like adults, and
with great
kindness, he also shares different aspects of his life from his memory game, to
his
love of the zoo, and his personal pig collection. He is so nice, that the
kids actually wind up
visiting the zoo with him in chapter six and a good
friendship begins.
