Would any of you give me some tips about making friends while

Taking the initiative is usually admired ... As long as your timing g is right.

It's an experiment tbqh, some will be friendly to cold approaches, some will be welcoming.

Never ever assume though that you know 100% how a person would react.

Don't be a shriveling wallflower in hostels. I'm a shriveling wallflower by nature, but with practice I've become able to make friends at hostels.
Most of these encounters happen either with one other person when he/she walks into the kitchen where I'm cooking (so what are you having for dinner? That looks awesome. I think I saw some oregano in the free food shelf if you need it.)
Or in the common room wherea group of people have paused conversation long enough for me to interrupt (so where are you guys from?)
The key is to keep the conversation going once it's started.

Option B is to travel to countries where all the locals want to be friends with you, like Morocco, Iran, rural UK.

Have found it pretty easy even as an almost friendless loser, atleast in SEA. Just sit in a crowded chill bar and you'll get invited over to some local or travler group.
Just last night I went to a bar for a beer after dinner, got seated next to a group of Vietnamese men, one of whom could speak English. Drank all night and gave me a ton of food, took me to a great pho place after, then we chilled drinking tea and eating sunflower seeds.

just do it lol

just be yourself desu
