I sent an email to a different friend with quite a lot of content in more than 24 hours ago and they have not replied, but have been on their social media a lot. Now I wonder if they find it a grrrr email what I sent. It wasn't intended to be grrr. It wasn't angry. It was complicated. I am guessing they won't reply (and I can guess why) They are a good friend. I don't usually send them ''complicated'' emails. (or many emails at all)
How do people respond if they get a gut feeling from an email that they can't quite put their finger on. Or a PM even. I guess the healthy thing is to talk it out unless it's someone we don't care about. Or not to assume anything other than it might be that person's ''snake'' (or some other ''part'' we don't usually hear from) or they are just having a grrrr day. Or to wait ....
If I never received a frustrating email I wouldn't assume it's because nobody cared about me enough to send a frustrating email. I prefer not to receive them.

But I'm grateful for those who communicate with me. (in the family of origin there was very little communication. Very unhealthy, imo)
I received an email from someone a bit longer ago who said that I had hurt her feelings before, and this time I had hurt her heart. (not anyone on pc). She was not reluctant to share how she felt. I'm more reluctant to tell someone I don't know very well that they have hurt me. (of course I could ''just be too sensitive'' as some have told me, mostly irl)
If it's someone I hardly know who sends me a grrrr email I'm more likely to just delete it. It's their stuff
