When oneof us is either symptomatic or hurting, the other is always there just for the asking. We have respect for the other's personal space. I guess whata I need to tell you is this. True friends recognise that we are human with human flaws. We are not perfect and grudges are a waste of time.
Love given in spite of our flaws is the basis for a good relationship with others.
We try to be honest with each other and not hide our true feelings. This gives us a measure of trust that I personally have found difficult to find in other so-called friendships. We have good days and bad days. We give each other space and we don't interfere with the other's family obligations.
