I have two nieces. They were born a year apart from one another. M is 5 and K is 4.
M is drama-queen to a T. She always cries hysterically when it's time to say goodbye, if someone won't share a toy, she pouts or throws a fit. SIL and BIL are good at checking her when she's out of line. I know most of it is the age.
K, on the other hand, is a sneaky little devil. She's always flying under the radar. She has M's number and knows how to push her sister's buttons.
K couldn't find her water on Christmas eve, so she took her sister's water and sucked it dry. M found out and threw a huge fit about it (she was over tired, they were getting ready for bed). Crying, carrying on, the works. SIL was on M's case for blowing it way out of proportion.
K is standing there, sweet as can be, saying, "Oh water. I love water. Ahhh! That was some good water."
I told her that it wasn't nice to antagonize her sister. M stopped crying to ask me what 'antagonize' meant.
Those girls crack me up. I hate that they live 10 hours away because they are so fun right now.
