her service time was short, but she actually did learn a few things about repairing motor cars and enjoyed her time in WATS. While not strictly necessary at that point in the war, she felt that she had to do something to 'give back' as it were to the British people. Not a bad attitude or position to take in my opinion and one that more than a few presidential, vice presidential and other government officials' children could do worse than to emulate.
