We have a saying in our family, I think it came from my beloved, “extend the tentacle of friendship”. I love that it implies a few things, the first being that each of us is a gooey mess, like the creatures in Galaxy Quest. Also that someone seeing the tentacle would actually allow it to touch them, which makes prospective new friends very brave. Lastly, octopus can grow back a tentacle if it’s chopped off making the risk very low if a person responds negatively to my tenuous & awkward attempt at a broken but rewarding friendship.
Assholes are notorious at failing to make friends so the alien/octopus image should allow you to see you aren’t that bad and maybe someone will extend the tentacle of friendship back to you. Try it. You might just like it.
