In "1984", how does Winston react to the note from Julia before he reads it?

His initial
reaction is distrust. It seems odd to him that a woman such as her would even know or care he
existed. Therefore, he had to wonder what was her motive? Was someone out to get him? Did
someone set it up so they would meet? This book shows paranoia to the extreme though this
paranoia is justified. When he finally does decide to read it, he has to read it in private and
dispose of the letter. This further demonstrates his fear.
