kids at my school

Kids at Yotsuba really really confuse me. One moment they will be nice and say "Hi" or wave, but most of the time it seems they dont want to be friends.
I really want to be friends with everyone, but it dosent seem like they are interested. Maybe because most of them have been to america. Its not as interesting to be friends with americans, i dont know........ anyways enough complaining. 
Yotsuba kids!!!! be friends with me!!!! im not trying to be a scary american i cant help it!!!

Im really really happy right now i just got to sit down with my host mom and just hang. I showed her pictures of all my friends in america and vancouver and portland and my parents it made me super happy. I was actually able to communicate with her. every time she would see my friends she would go "KAWAII!!!" and every i stopped on a pic of dad she would go "Emmas otoosan!!!!!!" and same for mom. i just love her :) kinda content right now, but also a little nervous i move to my next host family this weekend. Wish me luck!
