Met new colleague today. I assumed she was on work experience as she looked 18 and asked her if she was, to be met with a frosty "No. I am 35.' Absolutely amazed but also highly embarrassed as she looked angry. I then thought she sounded different so asked her where she was from as her accent was so strong and she said "Nowhere? I grew up here.' Again, really surprised but also embarrassed.
Got it very wrong on two counts and now feel really awkward. How do I come back from this?
