Not my story but someone else’s - two close family members involved. One had lent a large sum of money (five figure sum is all I know) to help them out financially due to a horribly expensive divorce.
there has been a fall out due to lending party asking for interest on loan as the loan will take a long time to pay back and lender is considering their financial situation and future inflation etc.
both parties single so no other people to rely on really financially. Lot of tension now.
being unreasonable - the lender, it’s family.
not being unreasonable - borrower, family member is doing a big favour here and is being very careful with the coffers.
I know my thoughts but love to hear others!
