Pregnant hugs

I'm not a very touchy person and it takes my a while before I'm comfortable hugging new friends. I have a very definite personal space zone. At this time of year, and especially this year because I (along with several colleagues) am leaving the school, there tends to be more hugging than I'm comfortable with. When it happens, I don't want to be rude, generally I do like the people I'm hugging and I will miss them, so I go along with it. However, today I found a friend I would happily cling to for ages. She's not my closest work friend, but we have worked together in the same team for several years. We were in the gym store room and began talking about last night's Year 6 graduation ceremony, then we both start tearing up. We went in for a hug and it was so comfortable and comforting. I put it down to her being pregnant and us both needing it. Two boys walked in, shook their heads and left again to keep stacking chairs; we kept on hugging.
