attach yourself (politely) to the person who comes to help
This probably explains some of the interactions I’ve had when all I wanted to do is to help someone in need. Not in the gym, but mostly in the streets. Like someone getting lost, and offering to show them the way. Or offering my seat to the elderly.
But really, being helpful sometimes is all it takes for give someone the reason to talk to you (and vice versa). Not that I managed to be in a relationship with this kind of a start.
And the other way is distasteful too! Going around helping people because you want to “fish for friends”? Yeah, you could do worse things, I suppose, but still pretty icky.
Some people though, they can be pretty classy about it and if done that way, and no one is harmed, why not?
