The HDB block that I used to be staying face the east direction. Every morning, housewives will be rushing to hang their clothes out at the balcony to sun dry. I had done my homework and identify the girls or woman I am interested. some of them do hang their undies out but some don't. You just have to be patient to wait for the opportunity and keep a constant look out for it. I remember I have tabulated the following ladies I had been eyeing:

10th floor - #1 2 sisters, #2 a SIA girl
9th floor - #1 3 pretty daughters, #2 1 rebellious ah lian, #3 2 different aunties
8th floor - #1 pretty malay girl with big boobs
7th floor - #1 lady executive about 30 years old
4th floor - #1 school girl, 35 years old auntie
3rd floor - #1 45y.o aunties, #2 25y.o newly wed woman

of over the years there are people come and go and the young girls would have turn to beautiful teenager. I have a good share of this neighbourhood when I was growing up...
