Groaning with horror at the thoughts of going out for a meal/meet up at night (retired now). Nope, shivers at the very idea.
The first time I was given a seat on the bus. I never thought of myself as old(er), but retained my composure and sense of humour and said to the charming young man " thanks, but I'll have to go and get my Botox done now". There was a lot of laughter, but none from me!
When the man at the tourist train in Granada (it takes you up the vertical hill to Alhambra, no way was I walking up that!), said, "Senora - you have a discount for your age, it is €3 off the price!" Okay...... thanks for broadcasting THAT!
When my brother (13 years younger) and I were on a jolly somewhere, a waiter asked him "what would your mother like to drink?" FGS I was sitting there and didn't know whether I was more annoyed that he thought I was DB's mother, or that he didn't ask me directly, doddery old fool that I must have looked to him. DB on the other hand must look like a teenager. Unfucking fair, sorry for swearing.
