Tonight I drank with my friends. We met in Australia about 1 month ago. During our talking, we talked about happiness.

I've been in Australia since 1st June. When I was in Korean Korea, I had a permanent job with a high salary. However I didn't wasn't happy during my working with my job. Besides, I didn't like the company's curture culture. After working, we went to bar [a bar or bars] and drank alchohol very heavily everyday every day (2 words). Acutually I like to drink alchohol, but I couldn't endure  ['endure it' is ok, but 'stand it' or 'cope with it' sounds better here] anymore. Everyday morning, I cound't couldn't {short for 'could not'] smile for my mother because I was drunken. [Oh! That's not good!] Back to my working, I couldn't show mom a smiling face except for only one time - my first day in the company.

Therefore I decided to quit my job for my happiness. I really want to show a smiling face to mom. Furthermore I want to be a happy guy.  [Good idea!]


We talked like this and other friends agreed with my decision. Then, the subject changed from happiness to mom. My friend said that he has supported his parents financially for about 5 years and sometimes he is proud himself. However one day he realized that his mother had supported him for about 5 times [not quite sure what you mean here] but she was always had a burden to his her son because she don't didn't give his her son more good things. When I heard this story from my friend, I remembered my mom and really missed her. Mom always give his her family unconditional love. Probably I can't give back totally to mom the love I've received. Mom's love is infinite. Tomorrow I'm going to call mom and say, "I love you!!!"

This is my diary. ^^;;;

Thank you in advance. :)

Great writing.  :)  Ahhh!  Lucky mom!  (Here in the UK, we mostly spell it mum - I think US spelling is mom, so maybe Australian is too?)
