That's the classic MBTI definition of an introverts and extroverts. We're both definitely the former. I miss Greg when he's not around but we often do our own thing in different rooms but like knowing the other one's there. It's like a huge relaxation of tension when Zoe is out for the night or away for the weekend, and I think a big factor in why I feel so exhausted lately come the weekend. Her mother however is an extrovert who is lonely without her kids and always seems to have someone around and thinks it's no problem at all for us (because surely it's the pleasure it is for her). I can't explain without looking churlish. It's really nothing to do with Zoe (except for her pickiness re flats), it's just hard having someone here for so long.
