Question -
When the two of cups is used to describe how another person views you what
does that mean?
Answer -
Twos generally regard a balance or equality. Cups address emotion and
emotional traits.
I suggest that if the cards around this one are indicating a reflection of
what you look like to this other person, that you try reading the Two of
Cups as an indication of their opinion regarding your emotional
stability -- and that would mean yes you are emotionally stable. If the
surrounding cards are pointing toward how the other person FEELS about
you, that you consider the card an indicator of a degree or set of
emotions pointed at you, of which, with this card, there are many
possibilities.
I've found and online description of the Two of Cups at learntarot.com
http://www.learntarot.com/c2.htm
which provides a complete spectrum of possibilities in specific meaning
for this card.
From your description of its placement, it seems to me that this card
indicates some strong feelings, if only strong because they are beginning,
but also some ambivalent, conflicting or balancing emotions. Without
knowledge of the surrounding cards, or if this is a single-card reading, i
would most likely look at this as a sign that the person is at a pivotal
point in deciding how they feel about you -- whether they think good or
ill of you -- but that it is clear, even to the other person, that there
is great potential in its beginning.
