Agree, that's why I am very picky on choosing friends.
Time will reveal a person's true character. I do not have many close friends but my close friends are all very trust-worthy. One of my good friends used to rent a room in my house for many years. Every month she would give me a signed check without any figures and asked me to fill out the amount (including rent and her share of utilities, the amount changed every month based on the usage of utilities and phone.) She never checked to see if I filled out the right amount. She has that much trust in me, how can I not return her with the same amount of trust? She is like a sister to me, when she got married, I brought her gold jewelry
