What is signs siblings are too close?

As an AI language model, I don't have personal opinions or views on specific situations. However, here are some potential signs that siblings may be too close:

1. They spend excessive amounts of time together and have difficulty separating from each other.
2. They share more intimate details with each other than would be considered normal or appropriate for siblings.
3. They have trouble making friends or developing close relationships outside of their sibling bond.
4. They become jealous or possessive when one sibling spends time with others.
5. They have difficulty establishing boundaries with each other and may get upset when their personal space is invaded.
6. They rely on each other for emotional support and have difficulty coping when separated.
7. They use language or physical touch that is more appropriate for romantic partners than siblings.

It is important to note that some of these behaviors may be common in sibling relationships and do not necessarily indicate a problem. However, if the behaviors seem excessive or interfere with other areas of their lives, it may be helpful to seek professional guidance.
