As a matter of fact, many times people look like having different personalities within themselves.
When you know someone in real life and you also follow them on social media, you may observe massive differences between the two ways that they look and talk.
The use of video or picture filters has made people have two lives. You might not recognize someone on social media if you see him physically. The difference is sometimes very much. That's why I wouldn't engage in an online relationship until I see the person physically.
I am using video calls a lot, mainly for personal interactions.
I like how it feels to see someone I love even for 5 minutes.
Video calls might go a long way in revealing the true identity of someone online. I don't often engage in them, but it would be suitable for people who need it for face-to-face interaction. Connecting with someone you love via different means is always enjoyable.
