Are there any differences between to get tired and to grow tired?

Question

Answer

to me, "get tired" refers to a point in time after which you are tired, and "grow tired" refers to a period of time during which you become tired.

Answer

Hey, in my opinion I would have to say: no there is not a difference. But, most people use "get tired" in conversation. I rarely every use "grow tired." 
Example: I got tired of watching tv. 
    (That is pretty normal)
Example: I grew tired of waiting.
    (Not used very often, more so in novels/books.)

Hope that helps.
