Strike up a conversation with a stranger

When you enter a room, look around!
Looking for approachable people, that is people who are standing or sitting alone.

Make eye contact, smile, and introduce yourself
A simple “hello” and “my name is” can get you to a good start

Use an icebreaker question
Depending on the circumstances, you can ask for the other person’s opinion of the weather, venue, organization, impressions, etc. Make sure to prepare some icebreakers in advance.

Make the other person feel comfortable
Be respectful, show genuine interest in what the other person is saying and respond accordingly.
