My hypothesis is this: My love language is touch. Touch, such as hugging, brings me happiness and comfort, and when I was a kid I thought everyone received love in this way. Of course, that isn't true, people express and receive love in many different ways, and for some people hugging them can be offensive. Such is life.
Unfortunately, hugging to apologize has now turned into profuse expressions of "I'm sorry" over and over and over again until, no matter how sincere I am, the words hold no meaning. I admittedly do the same when I say "Thank you". I mean it every single time I say it, but when said too many times, people seem to no longer feel the gratitude.
Currently, I'm working on different coping mechanisms to find a happy medium of expressing my gratitude, or my apology, without cheapening the expression and leaving it at that.
