I may be off but for me, I have boundry issues due to when I was younger it was always, "you will hug your aunt", "you will hung your grandmother", "you will kiss X", etc. It wasn't something I felt comfortable with but forced into doing it, and now I hold back due to I don't know if this is what I "want" or "have I been conditionsed to do it"? I have been lucky enough and a few people I do say bye too, hug or we have our way that we are both comfrotable with but those are my few true relaionships I have formed over the years. Learning my boundries and what makes me happy sure is key to my self love.
