My husband and I arrived in a new country just a month ago. We were sort of    about what was waiting for us. However, when we   at the airport, a tall man with smiling eyes greeted us. The days and months were   made easy for us by this kind man.
He greeted us every day with his smiling face. He   us in going to the bank, in buying our groceries, in telling us   to buy almost everything. He told us he is our big brother.
   , we watched the match in a coffee shop. During the first get-together, he   us that we’re lucky—my husband and I are   in this foreign land. He said he has been   for eight years now because he rarely sees his family,   they are in his home country.
During the second get-together, he   told us that we are his family. He said that he loves us and that he will   us because he has been given a   of 45 days to go back to his home country. That night, he spoke these words which   a great impact in my life:“You changed my life…”
That night deep in our hearts we were   by our friend’s words. We texted him upon reaching home,   him for being a Big Brother to us in the foreign land. We told him   that we feel safe in going out when we are with him, to which he   , “You are my family here.”
On the first week of October, we’re going to   him back from his vacation. We’ll watch the football match again in that   shop that holds dear memories.
