Since the beginning of unfortunate days, we have seen combinations of blue and yellow everywhere. I realise that the world is connected each other by witnessing how a place that I didn’t care until yesterday will soon change to a most known place in the world. French vaccination pass showed the flag with those two colours on it and a mark of my town is now coloured with those. A few months ago, I was concerning myself in a foreign place by listening to a sigh of my colleague originally from Africa about COVID-19 and it turns to be new before forgetting a nightmare.
