99 is a person that we cannot get rid of as long as we keep the marriage and she is still alive. I am not saying to blindly "please" her but at least put some efforts to keep a harmonized relationship. There may be some "difficult to deal with" 99s but I think these are minorities. I am very glad that I have very reasonable and nice 6299.
For me, I won't have any expectation from her and I never get disappointed. Everything she does for me is bonus. She offers help whenever we need. Some JMs complained their 99 didn't do this and that - what can you expect and she is not obliged.
I believe it is a give and take relationship. My hubby's family never celebrated birthdays for 62 and 99 before we got married. He said they didn't have this custom. I noted 62 and 99 would like some celebration but just didn't say. Since then, we celebrate their b-days every year and they are very pleased. We also held a small banquet for their 50th anniversary. We felt they were very happy.
We, as the younger generation, should take a step forward. Otherwise, we are both in the dead end.
