Is it bad that sometimes when I am on Tinder and I see someone not so very good looking (or someone who is ok but I think they do not get a lot of matches), I want to swipe right to them just so they could have a good looking match and hopefully build their confidence IF they dont have one (or too many matches)... but then I think, if they start talking to me and I'm not interested... that's not nice... Should I do it or not at all? Is it a not nice thing to do?
I would say: if you're at least wanting to be nice to them and allow them to be nice to you (without you looking away), it's fine. But of course you shouldn't send a positive signal first and than look away :o
It's a nice thought to have, but you're not really responsible for helping them build their confidence. If they really match as low as you think they do, then they'll definitely talk to you, and then what will you do? lol
