This morning I was putting my things in the car when a unknown man passed by. We looked each other (both wearing mask) and to break that uncomfortable moment we said "Bom dia" (Good morning") 😃
That is the minimum two unknown persons can do in this weird situation.
Although, and unexpectably, the unknown man surprised me with: "Tenha uma boa sexta-feira" ("Have a nice Friday"). I only had time to say "Igualmente" ("Likewise") and when I followed my way I immediadtely knew that man made my day better.
It is so simple to improve others others day! In my opinion we only need to pay attention, be polite and specially hear others with genuine interest!!
