Uncle-itis

When a niece or nephew begins to experience physical distress due to separation from his/her favorite uncle. This can manifest in the form of nightmares or oftentimes, severe crying. Only the reuniting of said uncle and niece/nephew will cure this disease.

Oh no! Maya and Odelia are developing a bad case of uncle-itis. Better get Rami back home soon.
