How can you talk to a girl when you are really nervous in front of her?

Your problem is extremely common. Most people are very shy and tongue-tied. Don't feel bad. I use to be super shy when I was younger and if someone of the opposite sex even said hello to me I would turn all red in the face. I got so tired of it and in my very first job I meet a wonderful older employee who told me this, "Take a course in public speaking. When you have to get up to speak in public think of all those people with their clothes off and sitting on the john." I thought this person was on drugs, but I got thinking about it and enrolled in public speaking classes. It wasn't easy and I messed up a couple of times, but then those Words rang in my ears, "All those people out there are nude and sitting on the john!" It worked! I'm glad I took those courses because in some of my jobs I did have to address board members at a board meeting, speak to other people from other countries and I was very comfortable with it. Other people are also very shy and once you realize this you'll feel more comfortable. Even if the other person seems super out-going most of the time it's a cover-up. Never try to be someone else, just be yourself. If you have a quiet nature then stay that way, and if you are more extroverted after you get to know someone then "let the sunshine in!" Remember, we are all chameleons (changing color) several times during a day. People don't really get to know what we are about until they know us on a more personal basis. Once home we are ourselves and nothing like that person out in the real world. People cover up all sorts of phobias and doubts in their minds as to what they are capable of and go through the motions. So, you aren't alone. Just walk right up to that girl, ask her out if you like and go somewhere you might enjoy. Perhaps you might be more comfortable with lots of friends around until you get to know this person better or you would feel more comfortable going to a quiet place to have a more intimate conversation. You are in control, so use it. Good luck Marcy
