Both are teens, and are finishing homework. DD2 is doing something for art upstairs and DD1 is doing maths downstairs, which when she asked me a question I look at re book and she is doing her sisters maths!
I tell them that they should be doing their own homework and all the reasons why, but apparently to them this is perfectly acceptable arrangement to them they have Dd1 hates art and likes maths, DD2 loves art and hates maths so they swap homework all the time
Apparently I am the unreasonable one in this arrangement
