Possible informal English greetings depending on time
I would like to code a simple text based game. Instead of one standard greeting I would like to randomly choose one from a list of filtered greetings depending on the current time. English is not my native language and I need your help to create such type of informal, friendly greetings. For example, if user logged in at 1 am the program should greet like “Hello nightbird” or something similar. The same things I’m looking for a friendly good bye.
