I am Person C and know Person A&B well, they are my family.
Person A was asked to suggest some ideas for what they want for an xmas present. They suggested two possible things for person B to choose from, this is what Person A&B routinely do though Person A usually says they don't want anything. Person B was asked to suggest some ideas too and did so. Person A is trying to avoid shops so orders two of the suggestions and wraps them ready for Xmas.
Person B contacts Person A and tells them they have transferred the money (about £20) in Person A's bank account and to go and buy one of them items themselves. Person B says that Xmas is going to be dull as everybody will have had their presents. Person B is going about their business as normal and going shopping whenever they feel like it.
Person A has now got the money in their bank but has depression and low self esteem and doesn't buy themselves anything. They have put the money in their savings account to be used when they need to buy their children something/for a rainy day instead of buying the item they suggested. Person B knows that Person A has form for never buying themselves anything and not spending money given to them on themselves. Last time Person B did this then Person A used the money to go towards school shoes.
Person A,B and C will be seeing each other on Xmas Day if Covid allows. They all live within two miles of each other in the same town. They are all approximately the same age and none of them have specific health issues that stop them from going shopping. All 3 are single, Person A and C have children, Person B doesn't. Person A doesn't enjoy shopping at all, Person B is at the shops most weeks.
Is Person A being unreasonable not buying the item or is Person B being unreasonable for not going and buying it when she goes shopping and wrapping it up to give on Xmas Day/dropped off with Person B if seeing each other on Xmas Day is not possible due to Covid.
YABU/Yes - Person A should use the money to buy what Person B has given it to them for.
YANBU/No - Person B should have bought them item and wrapped it up to give to Person A at Xmas.
I have had both Person A and Person B complaining about the other person, A thinks it would be nice if B went to the effort of buying it and wrapping it. B thinks A should just order it herself and get it delivered to her home.
