Some people have poor communication skills.
I know that with how we are all connected to our phone technology it took me a while to get used to getting a text then nothing. People used to not call during dinner or late at night. Now people just text at will. This is especially true when owing a business. Now there is no such thing as only calling or texting during 9 to 5 business hours.
We seem to live in a more on demand lifestyle and it can seem rude. It’s different now. No it’s not just you.
