A Gift of Chappals — English STD 7 — Question

For getting milk for the kitten, Ravi told Paati that he is hungry when she saw him with glass of milk. Paati got suspicious so Ravi had to drink most of the milk and told Paati that he will wash the tumbler by himself. After that, Ravi ran and pour the milk into coconut shell and then ran back to wash the tumbler before Paati got really suspicious.
