I agreed to collect DBD from school with DDs on the week that she is with her mum, mums DP collecting her from ours at 4ish, so just enough time for a drink and a snack before she's collected. No problem, I love DBD to bits and its not any more hassle for me.
Tonight when DBD was collected I offered to drop her back to her Mums house from now on what with the weather getting worse, it would save DBD and Mums DP a walk. The DP replied that as he was now starting work at either 4 or 5 some days it would be better if we kept things as they are as her Mum would be collecting her some days. Her Mum doesnt finish work til 5 so she wouldn't be collected til 5.30 or so. Had I been asked rather than it being assumed I would do it I wouldn't have an issue with it. As it is I am seriously hacked off that they are taking the piss
