Mother went out and left dad in charge of their 3 year old daughter.
The daughter was playing with her tea set she got for her birthday, it was her favorite toy. Dad was in the living room watching football when his daughter brought him a cup of tea which was only water.
After several cups of “tea” the woman came home. Dad made her wait in the room to watch his daughter bring him a cup of “tea”, because he thought it was so cute.
Mother waited, and sure enough, the daughter brought him a cup of tea, the woman watched him drink the tea and thank his daughter for such a lovely drink. Then she said to her husband, “Did it ever occur to you that the only place she can reach to get water is the toilet?”
