I'm assumin' this happened in-game, aye?
I'm sorry this has occurred to ye' Ms. Cheyann but it does happen. There will be times when other members may remove ye' from their friends list. Sometimes with reason, sometimes without, or sometimes by sheer accident. I know not as to why this individual removed ye' but I wouldn't show any form of hostile negative emotion towards 'em if the urge comes to ye'. Still, hearin' that they were, as ye've stated, a great friend of yers, I do hope that things work out. Even if they may not, there are still many floofs who'd be delighted to make yer acquaintance if one looks on the brighter scale.
