DP says no to teenage (15) DSD's current demand which are getting bigger every week
She won't come round because she can't leave her friend, her friends parents are not around today so she can't get in her house, so the friend must also come to DSS's birthday dinner tonight.
DP says no, come and spend time with your family, your friend can't come on this occasion, lots of whinging from DSD and now MIL is off to pick both of them up and bring them here.
She was supposed to come round last night and didn't because she went out with friends, she asked for money £25 and we said no (because she's had about £100 from us the past few weeks and her brothers have had nothing) of course, MIL gave her the money 
Just annoys me that we say no and MIL doesn't listen and gives into DSD. I know she's a teenager and will start to have her own life but we can't always give into her and I would like to think, DP being her father should get the final say and that's it.
And also, we've got enough going on here without having another kid thrown into the mix that I don't want to be responsible for!
Anyway, vent over
