If we're talking therapy boundaries, I'm back and forth. Emotionally I'm like "WHHYY? WHYYY?" and rationally I'm like "Thank God, or else I'd never live in real life"
If we're talking about in life outside of therapy... depends on the person. If a person I actually COULD be friends with imposes huge boundaries, I think that's a sign to me that they don't want to be friends. If they impose reasonable boundaries, then it's a sign they have standards. I dunno, depends on the situation.
