Let me introduce my family. We are five in my family. My wife was a music teacher, but she is housewife nowdays. We have three children, one son and twins daughters. My son who likes science is 7 years old, and his sisters are 2 years old. (I don't know what they prefer.... somebody tell me.) Actually we wanted 2 children, but God gave us one more angel :-) Although I and wife don't have much free time, we are happy to care of them. Thanks.
