what a spoiled kid

so we had this "puzzle sport mat" that lay on our living room. but the thing is this kid took the mat off along with a toddle, and I yelled at him for taking it off, and told them to put it back together.
well they did, but in the middle of doing so, they just slacked off and play or not doing at all. of course I yelled at them again. this kid at first was mad himself that the pieces didn't stick together, so I told him "see that's what u get for taking the pieces out, so next time didn't do that again, got it?"...  but later on he was mad because the pieces was stuck together, and he wanted those pieces to be unstuck....I was like WTH !!! 0.o  this kid wasn't listening to me when I told him to put them together, but he kept crying and wanted what he wants, so I just sent him away from the area and do the rest....
what the heck!! this kid is annoying....
