DP is not a solicitor or a banker but his career has strong links with both law and finance so he is a bit of a jack of both trades and a master of neither
We have some friends who ask us to dinner 2-3 times a year. They are currently involved in an ongoing legal case and every time we go they ask DP to go through recent paperwork and advise them. They also keep asking for his advice on their investments.
I barely get talked to except for pleasantries and DP comes away irate and stressed. Sometimes they end up phoning him a couple of days later to clarify some of what he said.
Theyv've asked us round again. AIBU to politely decline and make up an excuse (even though we're actually free and they are very good cooks) ?
