I feel terribly embarrassed both giving and receiving compliments. I would never be able to say something to a checkout girl about her nail varnish - or more likely nail decorations, which all checkout girls seem to have. Equally, if anyone said something nice about something I was wearing, haircut, or the like, I would be most embarrassed, in varying degrees depending upon who the compliment is coming from.
However, I don't mind complimenting someone on something they have done well. And I also like receiving compliments on achievements.
Like Grannypiper, I am bursting with inward pride which will turn into a big grin when I'm on my own!
