I promised my friends I would meet them at the swimming pool today.Last night Frankie and Lisa asked me if I would meet them at the swimming pool today at 6AM. I said I'd like to go, but I didn't think I could wake up so early. I am lazy Lan.
And guess what? I woke up right after I heard the alarm. We started swimming at about 6:30. The pool is an indoor pool, and the water was clean.After a really good workout (swimming about 1000 meters), both of us were really tired. We took a shower then headed to McDonalds for breakfast.
It was a good beginning to summer vacation.
