Besides her love for Donald, Daisy is also shown to be more sophisticated and intelligent than him. This causes her to frequently be frustrated with his immaturity, and their relationship occasionally has an off-again, on-again nature as a result, particularly in the comic books. In comics, when Daisy is fighting with Donald or temporarily breaks up with him, she goes on dates with Donald's cousin Gladstone Gander instead. In "Cured Duck" Daisy even gives Donald an ultimatum regarding his temper but later reforms in "Donald's Dilemma". Daisy herself sometimes exhibits a temper, but she has much greater self-control than Donald.
