A couple of people sit outdoors at a table with an umbrella and talk.
A man is arguing with a puppy about who forgot the umbrella while the stand on the train.
Talking and arguing are two different forms of communicating. Also if you have forgot an umbrella then one cannot be located at the table you are sitting at.
