How would life be with a twin?

The birth of twin siblings is a particular event, that stands out even more if they happen to be heterozygous.
Even though the majority of people is used to see themselves reflected in mirrors every day and interact with what can be defined as an exact copy of ourselves, this experience cannot compare to actually living together with a twin. Seeing someone that, to some extent, appears to be a clone of ourselves. Would that affect and challenge our own conception of personal identity?
This is a series of family photos, immortalizing everyday activities as they happen. Each photo portrays two people, me together with my imaginary twin, who is acting coherently to the situation but not just copying, not like a mere reflection. The set depicts familiar, calm and quite moments, when the mind may strain from reality and explore the possibility of being confronted with our “double”.
