Abigahid's prank

The last weekend I played a prank to my sister, she was very cross with me because I emptied the shampoo in a glass, I filled the shampoo bottle with cream, when she was taking a shower, she watched that the shampoo was very thick, but even so she took a shower, she shouted very cross, and she came out of the shower, all of us laughed because she looked very funny, in this moment I felt very good because everybody was having fun, but now I feel embarrassed because she doesn’t like pranks, she says that the pranks can cause accidents.
