Death is not unexpected on whether it will happen, but when. Everyone dies, but you might be going to work one day and you die because of a moron burning a red light, or you might ne the healthiest person and get an incurable cancer, or people die from random hearth attack.

That’s not true, “retarded” (from the latin term for delay) was intially used as a medical term to someone with lower cognitive abilities, not an insult per se. but like other similar terms (such as “cretin”) it was eventually used more as an insult, until it was considered offensive by most and only the offensive meaning remained in the common speech.

It depends on the amount of time, but if they don’t even have the time for a courtesy reply like “I’ll get to you in a couple of days”, or “please contact me in … days and I’ll be able to help you”, they either don’t care or are too unorganized to bother
