About italki teachers I'm very dissapoint about the italki teachers when you schedule the session they give you hope by agree the request.After that they send you msg they have another schedule or another excuses. I think its better before agree they have to check their time and everything before agree to the student.This cause a problem sometimes you fill like giving up.All the time same excuses same problem. I'm requeasting all the teachers to be carefull with their calenda's session before accept the session.

learning a language when learning a language needs a lot of patience.sometime your trying and trying after so many ours you end up with nothing.Or you can learn a word after one week you have forgot the words and its meaning. My self know I'm trying to improve my speaking skills to became fluently english at italki.I dont have anyone to practice.I'm trying to write notes and reading stroy books.sometimes when I'm stuck at finding teachers at italki or someting else in improving english language.I fill like giving up. But I never do.Because I'm trying and give hope to my self. I can see some improvement in my writing skills and I, m trying so hard to improve in speaking skills.I'm sure the way I have seen improve in writing the same it will be in speaking. so I advice begginers and intermidiate when learning a languages needs a lot of patiece and courage.And always give hope to your self dont wait someone to in couarage you.

my children when your a mother you have to think only to your kids.They make you busy happy and sometimes angry with their strange things. My children are my life and everything to me.Thank god I have so much time with them.playing with them helping their home work. I hope and wish when they grow up they should love and take care same as I do know when they are young.
