Well I'm early 50's and my MIL arrives tomorrow (until Thursday
).
Tomorrow we will have a late lunch because she has a long journey to get here and because she is widowed and doesn't make a Sunday roast any more I am pulling out all the stops and we are having a lovely double rib of beef with all the trimmings followed by a chocolate roulade.
Back to work on Monday so there is lots of ham and cheese, naise savoury biscuits, salad, ham, salami - things she likes in the fridge for lunch. I have also bought her favourite breakfast cereal, apples, welsh cakes, etc..
Monday which is always a late night for me will be a rotisserie chicken, coleslaw, salad, new potatoes, etc., Tuesday (she is coming for a performance/solo of dd's so we will be late home at 9.30ish) will be smokes salmon, prawns, pasta salad and green salad; Wednesday we are having chilli con carne and salad with garlic bread and salad becuase this was one of the ILs favourite dinners when PIL was alive.
I work full time but I have a guest and there will be nice meals for her even though over the years she has been utterly despicable. That's because DH and I are the hosts and in our home we try to host well.
