No harm can come from being over-cautious; you'll both laugh about it later.If your date cares about and respects you they will respect and reciprocate your concerns.A first date is not the time for a hike through the forest or any other remote rendezvous.
Letting your online dating partner know that you're giving someone else their contact is common courtesy but also makes sure they know people are looking out for you.
Keep your cell phone with you and switched on at all times.
Be suspicious if your date insists on meeting at odd hours unless they have a legitimate reason. If you can't drive to the chosen location then get a friend to drive you, take public transport or a taxi. Tell a friend or family member where you're going, what time you're meeting and how long you expect to be.
Give the friend a copy of your date's contact details and make sure you date knows you've done this.
If you change locations, such moving to a different bar or restaurant, call or text message your friend to keep them updated.Arrange to have the friend call you at a specified time, such as one hour into the date, to check how things are going.
