Professor not replying to E-mail

<p>Hi. I recently emailed my professor about helping him with his lab, but she has not replied. This is the situation:
A few months before spring break I was talking to my professor for help regarding my career goals. I was aware that I needed plenty of experience so I asked him if he was aware of any professors who may want help. He said that over spring break, he would need help and that I could assist him. He told me to send him an Email right before spring break and remind him. I did that on friday, but he has not replied. He was away at a conference and so I figured that he was busy, but since he did not reply, I sent him another email asking if he has seen my email today. I was wondering if the professor is hinting at anything? He is not in his office, and I am unsure of how to go see him face to face (short of just calling the prof).<br>
Thanks for any help.</p>
