Today is DC 8th birthday. DC is at school, and will get home at 3.15.
Parent 1 is self employed, has appointments all day and will get home at 4.30/5. None of these appointments are essential, they could be scheduled on other days.
Parent 2 said as parent 1 left "DC will be sad you're not home after school". Parent 1 was upset and said "thanks for that, that's made me feel really shit".
Was parent 2 being unkind with what they said, or was it just a passing remark.
