My earliest childhood memory

When I was a kid, I couldn't pronounce the word "McDonald(makudonarudo)". whenever I tried to pronounce the word, I say like "mamumomamumo". it was difficult for me to say the word. one day, my family and I went to Mcdonald, and my father told me he would give me the hamburger if I succeeded in pronouncing "makudonarudo". I tried to pronounce that, but I failed. I tried again and again, but mamumomamumo... finally, I began to cry, I cried just because I couldn't eat a hamburger. it's very embarrassing memory, but I am too cornered into writing the blog to keep this memory secret.
