Why is he tempted to keep Tricki on as a permanent guest?

Explanation

Mrs Pumphrey had started bringing around eggs to build Tricki’s strength. Later, even bottles of wineand brandy began to arrive. The narrator and his partners started enjoying the eggs, wine and brandy meant for Tricki. According to the narrator, they were days of deep content for them—starting with the extra egg in the morning, then the midday wine, and finally finishing the day with brandy. This was the reason why the narrator was tempted to keep Tricki on as a permanent guest.
