朋友........的"有效日期"

I agree with you!  I believe that everyone has expired date, but no one knows the exactly date.  How to keep longer and longer, I think it depends on both.  And then Everyone is changing by time to time, it due to their mature/opital and individal experiances and some of unkown factor.   

Acceptable and kind are important to develop friendship.  Trust with each other, less demand.  Sometimes, you though she is your 朱古力"朋友, but she may though you as a 朱古力"朋友 or 麵包"朋友.   Or  You treat her as a 麵包"朋友 or 朱古力"朋友, but she though you as a 朱古力"朋友 or 咸甘桔 "朋友.  When you know that different and expectation what not same as your think,  you might feel a bit disappointed or upset, or maybe want to  leave her alone.   

Everyone need to have friend, even he/she is good for you or not Or treat you good or not.  It is also good experiance to observe that what friend do you like to with and know youself more.   Sometimes, you thought her as causal friend, maybe she/he could give you some suprise ideal to think on some decision.  Or You thought as a best friend, maybe doing somethings that made you feel discomfort and unexpected bad thing.  Be classified friend role can be changed by time to time, due to both work together.   Lazy relationship, get lazy result. :)

Take it easy!  No demand, good unexpected result :) is waiting for you!
