I had some friends back in v10. I lost contact with most of them after taking a leave of absence. I remember Kari, Zoey, Blockbuddy, and Marshmallow. There were two other people that I don't remember. I got contact with Zoey and Marshmallow after being gone. I never really talked much with Zoey. Marshmallow went inactive (when RTB folded, my friends list read "Last online: 1 year ago"). I tried without success to trace Kari. Blockbuddy was rarely on anymore and we never met in game afterwards.
Blockbuddy was my very first friend in Blockland. We would join servers together and cooperate to make servers. He hadn't been playing too much longer than me (8k BLID) and we generally just enjoyed each others' company.
Of the rest of them, I really enjoyed being with Kari more than the rest. She was a year older than me and liked Family RPs. I ended up building things for and with her and she was always willing to be at my aid since she'd been playing longer than me (1k ID).
