The main activities people in Japan do for entertainment include watching TV, gaming, eating out, travelling and playing sports. During the pandemic, people tended towards indoor activities, but tourism and events have been clawing (their way) back the popularity. Having said that, TV is still thriving in Japan. Variety shows entertain wide age groups with news, gossip and jokes. It is interesting that TV has started collaborating with the internet to retain viewers. Deleted scenes or bloopers are posted online. At the same time, it seems to me that more and more TV programmes are trying to break the boundary of the screen to make viewers feel like they are there together. One of the most popular TV shows today is a talk show where TV personalities chat about this and that in a natural, casual manner, while drinking. This kind of shows creates a feeling that it's just happening right next to you. As if you were sitting at the table of the popular group.

Both of these are acceptable in common parlance. Most common to hear is “How’s your wife and son?”, even if one is technically correct.

Hi, can I send you a message on Wednesday? I am not sure now because I need to go back to my hometown on that day. Thank you.

There is no difference in meaning here; "slip and slide" is a common phrase.
