Johnny was in a closed door meeting and suddenly his phone rung. His immediate response was to cover his cellphone with his hand and then asked to be excused. Why did he cover his phone with his hand?

PS: Please explain it briefly but the thought is very clear and easy to understand. THANK YOU SO MUCH!

Johnny covered his phone with his hand during the closed door meeting to prevent the ringing sound from causing a disruption or distraction to the other participants in the meeting. By covering the phone, he muffled the sound and minimized any potential interruption. This shows professionalism and respect for the ongoing discussion.
