not acknowledging but not excluding?
596241
Is there a difference between failing to acknowledge and failing to include?  Is that your question?\n\nI guess so, but it's subtle.  \n\nIf I'm not on speaking terms with you, but throwing a baby shower for a mutual friend, I may invite you.  I might not make a big deal about you being there and you may not feel acknowledged, but you have been included.\n\nI could speak to you in a group of mutual friends but exclude you from joining us at my house for a party.\n\nAh.  I guess agnosticism would be close.  I think strictly speaking agnostics believe there is a God, but that we can't really know much about Him.  Not enough evidence to convict them to make a commitment.\n\nEven though I didn't understand your intent when you asked the initial question, if you look at the first part of my answer, I think it still applies.\n\nWould you want a friend who failed to acknowledge you or who excluded you?  Either way you go, we don't like people to treat us this way.  We want for people to be happy to see us and to acknowledge us and our friendship in public, to include us in their lives, to be close.  True friends are loyal and stand up for each other.\n\nJesus wants the same things with us.  He is a true and faithful Friend.  He hurts at being snubbed much in the same way we would.\n\nIf you won't do it to a friend, don't do it to Him.

That's one possible "benefit" of being GLBT. We aren't (most) immadiately identifyable. Some times you can bounce between the two world and most of the time it isn't anyone's business. Sometimes you benefit from not being identified. Its not fair but most people do it (straight or gay) to some extent. Acting like you know more about cars so you don't get gouged by a mechanic for example. I don't get offended. But its not a compliment to be called something you are not.

They omit it so it won't be confused with the number one.

Not a thing. Why should that matter at all?

a simple hello would be in order. Ignoring the person would be rude, since you do obviously have some history with them. No need to act like dear old friends, but a hi, how are you? never hurt anybody.

Are they being disrespectful openly?  No

"except as otherwise explicitly provided" = unless we say so.

indecision or skepticism if you're not including the question mark.

Is none of the above an acceptable answer?

If your brother introduced you then I would imagine that he doesn't have a problem with it. You may want to casually mention that you are seeing the friend, but I don't think it is a must.

Well, it is odd when the interference has not been requested, as we ought to know that such a thing encourages others to interfere in our business.  But here in Yahoo! Answers, people ask very personal questions at times, and I figure they are looking for real advice.  If that is interference, so be it.

Ask them. If they won't tell you, they don't want to be called and you should respect that.

You are leaving something out.  We need to hear the whole story and not omit any of your wrong doings.
