> An ukall tree won't become a titimel tree.
i.e., a child will resemble its father; human nature will not change. The ukal, a lumber tree, resembles the titiml, a fruit bearing tree, at least to the extent that both are trees and become quite large. Both have assets but are quite different. The idiom is applied in the sense that a child resembles its father and will become what its father was. It may also be used to mean "human nature can't be changed."
