Receiving the Holy Spirit

I was with a childhood friend Jewish friend named Paul. He had his two young children with him—a boy and a girl. I asked his children if they wanted to receive Christ. They said yes, and I placed my hands on their heads and prayed for them. They both felt and received the Holy Spirit and were saved. I then asked Paul the same question, and with some apprehension, he said yes. I noticed my mother standing directly behind him. She was yelling at both of us and denying the words that I was speaking to Paul. I placed my hands on his head and prayed into his right ear. Afterward I asked him if he had received the Holy Spirit. He said he had felt something but was unable to hear the words that I had prayed.
