I was one of those people who had an online girlfriend in XI; I was 15, she was 12, she was a good friend's little sister...a fact I didn't know for quite awhile. You see, she started as a Tarutaru on his account and later got her own setup and made a Mithra, one day the three of us accomplished something and I said "We should help your sis through this when she gets her own account." after a short silence "....We just did."
I felt kinda funny that his little sister and I were...whatever you want to call that, and I was a tad annoyed that he didn't tell me for a few mins but it's not like I'd have felt any different had I known, he told me he didn't mind if she was ok with it.
Anyway, I miss her, she was awesome.
EDIT: Feels & stuff. ._.
