Happy to do my granddaughter's pickup, but 'back by 7' keeps becoming 9
I collect my granddaughter (7) from school four days a week and keep her till her parents finish work. I enjoy it and I'm not stopping. But we agreed on 7 pm, and lately it's 8.30, sometimes 9. I still do some advisory work in the evenings and by then I'm tired. How do I say this without sounding like I don't want her? Last time I mentioned it my son said 'just this week, amma'. That was three weeks ago.
