Maybe for that moment you a) needed a reminder and b) to be there because maybe someone nice and non-judgey needed to be there for whatever reason. Maybe to help someone else feel a bit better? Hopefully you'll remember for next time, and at least you got to chill with other friends and good music afterwards :)
I think I need to elaborate on how my friend is kind of a drag and that we only hang out now because we’ve developed a kind of trust in each other and don’t need to see each other every day, but you are right. I will have it clear in my memory now
