I don't believe a single word

After visiting my dad the last time, I realized that there is a limit to how much shopping can John (the caregiver) do.

So, I went to my parents neighborhood, entered the local supermarket, and started walking around the store, trying to think what is needed and/or could be of use in my parents home.
I managed to fill a decent size shopping cart.

I checked out, paid, and had the goods delivered to my dad's home.

The shipment was supposed to arrive 4:00 PM, but arrived only 7:45, several minutes after arrived, to spend the night next to dad.

Dad heard the noise coming from the kitchen, as John & my brother were putting the goods away.

'What's going on?'

'I went shopping, and the delivery just arrived' I replied.

'I don't believe it.'

'Come,dad, You want to see for your own? Let's go to the kitchen, and I'll show you'.

I then dragged dad to the kitchen.

'What's going on?' he repeated.

'I went shopping, and the delivery just arrived' I replied. 'John and Kim are putting the goods away'.

'I don't believe a single word' was all that dad said.
