Coincidence or is he mirroring me?

I’ve been lately posting snapchat videos of me being on a lake or other water scene. Also last selfie that I posted I was wearing a striped shirt. Now a guy that I kinda know has started also post about him being on a lake or other water scene. Also he posted a selfie of himself after a long while and he was wearing a striped shirt too.
