Hey, congrats on the first few days not being quite as stressful and you were sure that they would be! That's great.

I hope your stress will continue to go downwards now that you are back.
((As to mine - my tough bunch of kids have been behaving awesomely so far. I've even got the toughest of the kids to participate and do the work that everyone else is doing! We did, however, have to practice lining up and walking down the hallway. hahahaha))
And one person to sit with at lunch is 100% more than sitting with no one.

As the term goes hopefully the two of you will each meet more people and the group can grow! ((and, if the two of you notice anyone sitting by themselves... especially if you recognize their face....go and sit "near" them and then invite them to join you - cause it'd most likely mean that they're pretty shy too!))
