To succeed in a business, one needs to know math. To what extent do you agree or disagree?

Dear Joe, it's been a couple of weeks since I left your town and I can't forget the incredible moments we shared together. To be honest with you, I feel quite nostalgic as the memories we made refuse to move out of my mind. Actually, during my stay, I was mesmerized by the scenic beauty of the beach resorts we visited together. Besides, the souvenirs I purchased at the duty-free shops in the vicinity of your neighborhood were appealing to my siblings. By the way, I can never forget the rainy day when we did sightseeing. Had we taken umbrellas with us, we would have been able to stay much longer. Anyway, the walk in the rain was much fun per se. Although I missed you to death, the good news is that summer vacation is around the corner. So, why don't you pop round to my place? It'd be great if you came in July, so that we would be able to attend Kivodir festival in which local people do fireworks and make a bonfire at night. Moreover, a wide variety of summer fruit drinks and shakes are served. I'm pretty positive we're going to have a veil of time. Hope you can make it because it won't be the same without you. Get back to me as soon as possible. Take care, Sepideh
