Butting into a conversation between two people is rude.

What if one of those taking part is bored and needs an escape route?

Your interruption is a lifeline.

An interruption in your daily routine. Annoying.

It might be an escape route.

The phone call that comes when you are deep in thought. Breaking your concentration. You sigh. Reluctantly taking the call.

With negativity in your mind are you missing an opportunity?

It could be good for you.

Buck your routine behaviour. Coffee instead of tea.
