How Do You Know That I Love Your Mother?

I asked my 7 year old son how he knows that I love his mother. Below are the answers he gave

1.       You talk to each other a lot.

2.      You watch movies together.

3.      You buy her presents on her birthday.

4.      You are always together.

My follow up question was “Do you like it?”

His answer “Yes” “Why”

“Because I know you will be together a long time”
