This post says all that needs to be said. Anyone who would fail to respond, even briefly, to your follow-up is someone you don't need in your life. Blech. From this & your other posts, it appears she is all take & no give, & it's always all about her. Wow. No wonder you started this thread. While her response seemed just fine to most of us with no context, context is everything, isn't it?
You are a very busy woman & my hat is off to you. That she couldn't take the time to even respond is beyond unfortunate. Who needs "friends" like that??
