I'll try and keep it short.
SIL (single parent) wants to go and view a house for a possible exchange tomorrow, and DN (7 and home educated) said she didn't want to go. I said I'd look after DN. This means taking a day off work, but as I'm self employed this is do-able if necessary and I want to support SIL. So I haven't scheduled any work for tomorrow. I messaged SIL last night asking what time she would drop DN off and she replied saying DN thinks she might want to go after all and she would let me know tomorrow morning. I said this wasn't ideal as I didn't really want to take a day off work for no reason (I'm a gardener, so can't just turn up without arranging with clients in advance) so could she let me know by this evening please.
SIL sent me this reply overnight... "I'm sorry but I can't give you the answer you want right now. I won't know until it's time to leave whether DN is coming with me or not, she can't decide and we will see how she feels in the morning. You said you'd look after her so if you aren't going to stick to your word and want to go to work instead, just say so and I'll know not to rely on you again". DN doesn't have any SEN etc, but SIL has a parenting philosophy that children should make their own decisions about pretty much everything. Up to her, of course, but this is making me really frustrated as whilst I'm happy to take a day off to look after DN I'm not happy to be in limbo til it's too late for me to do anything else - I'm not well off, taking the day off is a favour to SIL because I want to help her out, but not something I want to do if it isn't actually necessary. I think under the circumstances SIL should tell DN what is happening not wait for her to decide last minute. She's welcome to centre everything round the whims of a 7 yr old but it's not really fair to impose that on other people who have offered to help her!
AIBU here?
