The GUEST-OTHERNESS is an interactive installation made in 18/06/2019. The print with the name, surname and title of the work made in etching technique refers to the signatures on the doors of the apartments. The doormat soaked with paint is a "trap" for guests. Traces create a record of their presence. The table is an element of work integrating, enabling the presentation of cutlery, tableware and tablecloth. Bans and orders were nervously scratched on the transparent cloth, other suggestions of more balanced character were engraved on the surface of the cutlery. Transparent dishes do not prevent reading the inscriptions. No food was given during the presentation, although the assurance of the well-established slogans suggested it. The relationship between the guest and the host consists of intuitive and obvious rules, full of understatements is the result of different educational patterns, material situation or social position. The ritual nature of those meetings makes the phenomenon of hospitality complicated and solemn.
