That person claimed themselve CEO on Facebook. Their occupation according to their Facebook page is "Stay at home Parent" - i.e. looking after their own kid(s).
Although it is very important job (to look after your own kid(s)) - calling yourself CEO is a little bit over the top, don't you think? :-)
Or maybe not. Now you can follow the suit and if you are staying at home and looking after your kids - call yourself CEO! I can't as mine are adults and I am looking after my business as Company Director (being humble..)
