However, approaching and talking with a stranger can be done easily..persuasively.
Essentially, you are saying "I like you"..asking "do you like me"?
If you are on a personal connection, like at home, you can run an anti-virus scan on your device to make sure it is not infected with malware.
If you are at an office or shared network, you can ask the network administrator to run a scan across the network looking for misconfigured or infected devices.
This gives the other person all of the "power" and "influence" in the situation.
They are in a position to "take you" or "leave you", without you having much more say in the matter.
After almost 2 years I'm impressed with the fact that these thoughtful gestures are still sincere, that they continue to grow despite being simple, just how much they really mean and how little effort they actually take.
