You can start this in an interesting manner like u and uor friends were together goin to a holiday in Switzerland or the place u like. then u can tell about the experiences in the plane and on the destination. u can tell about the food, clothing, tradition, shops and uor hotel the malls u went there etc. then u can add a little emotions and make it tragic that u met new friends there and that u did not wanted to return but had to. at last you can say that "its true that i had to return but its memories will always be in mind"
and a little pic of that place
