Although I do hate when people come up to me to practice their English, especially just when I want to relax after a day of teaching or traveling. I have still found I've become more outgoing.
I'm with you on that. It's not so bad if their English is good enough to have a conversation but I'm not a big fan of giving lessons at the park when I'm out with my kids.
However, I do it.
Sucker, I guess.
