Alex is home with me today with pink eye. He kept stealing my phone (which does not have keypad lock) and playing with it, so I gave him an old cellphone that isn't used anymore. He opened it and held it up to his ear. Then, he held it up to mine, so I pretended I was talking to Marcelo. I said "Hi, Daddy!" and Alex got all excited. So I put the phone to his ear and he starts grinning and saying "dadadada!!!". He got pretty upset when he realized it wasn't really Daddy. So, I called Marcelo and put the phone to Alex's ear. He held the phone, smiled and said "Hi, Dada!". :) We were both pretty blown away.
