The friends who knew you at your most awkward might not fit who you are now. Thank them anyway.

CREATIVITY
Some people were right for a particular stretch of your life and are not right for this one. That is not a betrayal by anybody; it is what happens when two people change in different directions. What they did was real though, and being known while you were at your least impressive is not a small gift.
Say thank you for something specific rather than letting it fade into nothing. Name the year, the thing they did, why it mattered. You can do that and still let the friendship be what it now is.
Who stood by you at your most awkward and deserves thanks?
Free, with nothing to buy inside it.
