Fantasy Days With Love or Lust

[me.you]

i am bit confused here.
kavya is 38 yrs old
her son is 18 yrs old
.. it's fine till here. then she has a brother who is 20 yrs old. it's a bit odd but it's possible and i have seen examples where an age gap between sibling is almost parent like. well whatever it's ok.

but what really puzzelled me is she got married at the age of 28.
so how can she be a mother of 18 yr old boy by the age of 38 herself.

am i missing something .. i would say her age should be 48 then everything will be fine.

if it's a mistake or a past-present thing in story narration then it's ok. but do clarify.

so so sos sorry.. Thanks for point out my writing stupidity.

totally its my mistake, But please read with this mistake.. Bz i need her son to be 18. and she should be 38 only. Please tolerate this mistake and i will not make any mistakes in future.

If i say she get married in 20s that will be another amature relationship. I dont want like that. She get married in matured age 27. with her husband , she fell real love with him. Not Just another infactuation.

Its my mistake again. If i want to change that, Please let me know.

Yes , her brother born when she was 18.
