(no subject)

Not wishing to mention any names in public but somebody on my flist banned me yesterday. I'm tying myself in emotional knots. We had what I wouldn't call a fight, more like a disagreement on her LJ last week but afterwards we had several perfectly nice, friendly conversations, (on both our LJs) including talk about her coming and visiting me, the most recent one being day before yesterday, so I thought she wasn't mad at me anymore. Is that a stupid assumption? Then yesterday I get banned with no comment or warning at all from her?
Do I just not fucking get people?
