Why would owner not make official announcement that business closed?

i had worked part time at this small business , it did online auctions and had one maybe every month or so. the last one i did there was in August and owner told me she was closing business and not doing any more.

well there has not been any auctions since as she said and building that used to house business as dormant and no sign of activity.

but website and facebook page still up and nothing has been posted since August , never been anything telling the customers she retired and business closed. which seems really odd by now

all i could think of was there was some reason she was claiming it was still open , perhaps related to income tax or something on paper as to why she doesn't want to yet officially close it.

people around here wonder what happened to it and i don't know what to say
