How does Miss Havisham show Pip in Chapter Thirty-Three that she has a heart?

The only real indicator I can detect that Miss Havisham shows any real feelings for anyone in this chapter is that Estella is requested to write to Miss Havisham as ahe has been allowed to make her way in society. This indicator is twofold: that Miss Havisham is allowing Estella some experience of the real world which she has never known-

" I am going to live," said she, "at great expense, with a lady there, who

has the power - or says she has- of taking me about, and introducing me, and showing people to me and showing me to people."

Also, Miss Havisham has asked Estella to write to her -

"I am to write to her constantly and see her regularly,"

This shows Pip (and the reader) that Miss Havisham is allowing Estella to be part of society, and that she cares enough to wish to keep in regular contact with her ward.
