Here's the scenario. This happened to someone I know and I need your valuable opinions. Thank you in advance for sharing your thoughts.
Gift giving parties: A and B
Gift receiving party: C
A and B together decide the budget and share amount (how much each person will pay, say $P) and the plan is to buy thing X as a gift.
Before gift giving time, A changes mind, goes on and buys gift Y, spending more than the budget amount increasing the share amount to say $Q. The payment for gift is done by A.
When it comes to present party C with the gift, only A goes and gives the gift, without including or informing B.
What should A do?
What should B do?
That's in regards with settling finances.
