Yes. I often think of my high school best friend and uni best friend, but I haven't talked to the first one in years and I only see the second one once a year. Sometimes I've wanted to tell her how much they mean to me and how much they've changed me but it's weird to say out loud. Once I almost let out an "I love you" to the 2nd one and made a last second recovery because it would just have been awkward, having to explain that I didn't mean romantically love and all... To sum up yes, I do think of them and I'm aware exactly how much of me is actually them.
They disappoint me
