These are relationships between equal partners which can be called acquaintances rather than friends. There are no visual obstacles in the development of these relationships, partners can talk easily almost about anything. Look-a-like partners do not feel any danger from the other partner. The strong sides of the partners are different in the such a way that almost any conversations between them always fall into the area of the confidence of only one of the partners. Look-a-like partners also have similar problems which makes them feel rather sympathetic towards each other instead of being critical of each other's vulnerabilities.
Understanding between partners is usually good. Collaboration between them may be very fruitful especially if partners feel a mutual attraction. When partners loose their feeling of sympathy for each other through anger or any other reason, they can apply pressure to their partner's vulnerabilities. This can sometimes be really unexpected and unpleasant for both partners.
Arguments in Look-a-like relationships are not common practice. The partners usually try to help each other, or at least feel when their partner requires some form of assistance. However, in many cases the help is not effective enough because partners have similar problems. Look-a-like relationships have an average degree of comfort. Partners do not have anything against each other but also nothing for which to struggle. These relationships can normally bring a feeling of satisfaction from interaction with an equal and not boring partner.
