Completely over the top reaction.
I get that some people don't do groups. But equally, can they understand that some people struggle with one-to-one situations?
I'm quite shy with people I don't know all that well, so a 1-to-1 would be really, really off-putting for me.
What if we don't hit it off?
What if they're quite shy, too?
What if there are awkward silences?
What if we run out of stuff to say?
If the conversation doesn't flow?
Just no. I'm a 'more the merrier' type because I'm quite shy, and because I pick up on other people's feelings and levels of comfort.
Group situations take the pressure off immeasurably.
