Holding hands is a common way of showing affection and support between romantic partners, but it can also be a sign of close friendship. The act of holding hands is a personal and cultural thing, and what might be considered normal or appropriate in one group or culture might not be the same in another.
In some cultures, friends of the same gender or opposite genders may hold hands as a sign of friendship, support and affection, others may not find it appropriate. Consider the context and the culture in which the friends are in and also the personal boundaries of both individuals involved.
It’s important to communicate with your friend and respect their boundaries if they are not comfortable with holding hands. Be aware that some people might not be comfortable with holding hands in public, regardless of their relationship with the person.
In general, it’s best to communicate with your friend and to be aware of their feelings and boundaries regarding physical touch. It’s important to be respectful of the other person’s feelings and to be open to the possibility that the friendship may change and evolve over time, and to be understanding if they don’t feel comfortable holding hands.
