I feel sad for you but I've learned to live happily and adapt with the festival here. Just because you miss dashain doesn't mean you be sad, common folks, be part of the society where you are living and you will equally feel festive even on christmas, new year, thanks giving, you name it. I know you miss dashain, so do I miss my culture there.. but .. just saying.. :D
thanks for reading these words .. Happy dashain to all
