my ashamed memory.

I had never been more ashamed in my life. i had gotten a bus as a child for a week though i was an adult. Do I look young? Oh dear..This is my first visit to Scotland.i stayed there for one month last summer.i went to Perth University during my stay by bus.at first, i could not realize that my fare was cheap ,compared to my friend's fare.but, the ashamed day coming unexpectedly,the day i got a bus after school with my friend, and i paid a taxi fare..(to be contitnue)
