I have known this person for some time just lately we have got back in touch, been going for lunches a few times, but I find her very strange, when we do go for lunch she will sit staring at me eating and not saying anything, to the point I don’t know where to look, and when I talk to her she will zone out, yesterday we went for lunch I was chatting away and she just got up and put our dirty plates onto another table, I thought how bizarre. Anyway she invited me out tonight to a party, I’ve decided I’m not going, so I did the right thing and messaged her this afternoon to say I won’t be going, had no reply, nothing, now if I invite someone somewhere I will think oh I wonder if such and such is coming, I better check, then I would see the message, am I right in thinking she seems abnormal? Also in the week she messaged me asking how I was I told her I was off work on holiday, all was fine, then she messaged me 2 days later asking how I was and how was work, but she must have read my message to see I was off work am I right thinking this is bizarre behaviour?
