>>81481That depends on you and your appearance, as well as where you are.
If you're on your own in a red light district, hanging around nudist resorts or on your own in a 5 star hotel surrounded by honeymooning couples, then people may be suspicious.
From my experience, people act a lot nicer to you if you look like a traveller, than if you look like a tourist.
I'm not usually a particularly outgoing person, I can talk to anyone if I have something to talk about, but I'm not great at small talk with strangers. But when you're travelling, you've got so much to talk about... you can talk to any locals about the area you're in, about their country etc. and you can talk to any other travellers (whether they're alone or not) about travelling (where they're from, what they've been up to etc.).
More than 9/10 times you'll get a friendly response, because almost all people that travel (travel, rather than 'holiday') are interesting, down to earth people who want to see the world and meet new people, just like you. So unlike going out on your own where you live and talking to someone, you know that you've already got something in common.
