Milk...

Today, while Timmy was drinking milk, he suddenly asked me:
Tim: "Mom, why is this cow's milk?"
Me: "Yeah, cow's milk is nutritious and is good for our body."
Tim: "How does cow gives us milk?"
Me: "We gotta milk it."

We ended up searching the internet on how to milk a cow. hehehehe...

We saw the videos comparison on the difference between manually milking cow and via the machines. Cool! When they were about to put the vacuum on cow's, Timmy said: "Hold on cow...tahan ya..." and he held his breath.
