Sometimes our little boys want friends but don't know how to make them. They find all the unspoken stuff - the body language, the shared obsessions (Dr Who etc) and the rough and tumble absolutely incomprehensible. A really nice, bossy, chatty, determined (and compassionate) little girl can cut through all that, she doesn't rely on unspoken rules or body language, she tells them what to do, tells them kindly but firmly how to play and won't take no (ie 'I'm terrified and lost and don't understand') for an answer. Sadly my ds's friend like this recently moved to the other end of the country
