She was not a liar

Taking mother to honeymoon is not done by any sane individual. It is an eccentrics’ act and exceptional behaviour.
These kinds of eccentrics’ act and exceptional behaviour could not be quoted and construed as general behaviour /trait
of males / females.
In this example quoted, either son or mother or both, would belong to special category (not of sound mind)
These are all cases with lack of proper enquiry before the marriage.
