There is a story behind this but it is dull and so I'll keep it to the bare minimum.
DP has essentially told me it is my fault he didn't get any milk when he popped into the local one stop for "supplies". He claims he didn't know we needed milk even though he has been making cups of tea today. "How was he suppose to know" he asks... because he has eyes and a brain too, surely?
It's not a massive deal but him telling me it's my fault due to my poor communication skills has filled me with silent rage.
