There is no ESTA to fill in going to the UK from the US (that I'm aware of anyway). No rules were being broken either. Just being too honest and excited coupled with not fully realising she should've just said on holiday and nothing else. I get to deal with changing rules and paperwork and being at the mercy of the mood of an immigration official all the time too, so I don't think it's just you or a certain kind of person.
