cumbersome - difficult to handle because of weight or bulk
or in other words, clumsy
then my another friend who only want to be known as Cpt Peng (a nickname I gave my fren! Not an actual army personal! ) consoled me with this picture

reminding me that I was once not so Cumbersome ! and LOOK what long NECK I got there !!! I am glad that I send Christmas Card to Cpt Peng every year !
