I love when I'm in storytime and one child is trying to hold another child's hand. They're desperately trying to say "You are super cool. I want you to be in my life!"
Oh, if only we could all be five years old and comfortable another to walk up to one of the other people in our Zumba class and try to make friends. Not walk up to hold hands or give them a hug ... that's just doomed from the beginning. However saying "Hey! I like when you make jokes when things get too hard. Can we go out for coffee sometime?" That gives me anxiety just thinking about it, but I know its possible.
Go out an make new friend today! Too hard? Let your friends know that you love them!
