Maybe I'm sensitive, but it comes across as judgemental. 'Call mom' - I can almost feel the condescending do-gooder smile from here.

I have one of those hurtful abusive mothers and I can see that OP was just being nice, repaying a kindness he felt 6yrs ago like he said. You are being sensitive of you can't see that.

Totally see where you're coming from, but I do think it's a nice reminder during quarantine. Time is passing so weirdly now, it's hard for me to keep track of what month we're in, let alone the date.

To me, it’s just recognition that the type of people who frequent this site aren’t always good at remembering this sort of thing. It doesn’t apply to everyone, but I’m sure there are people who saw this and appreciated it.

>"today might be a good day to call your mother"

The OP doesn't qualify their premise with 'might'. ('May' only applied to video chat, specifically). The title is imperative, and there is a general claim of importance.

I'm not bothered personally, I just agree with chriseatons assessment of the tone.

The pedantry on this site sometimes is insufferable.

It's a little reminder for the oblivious and workaholics among us. Nobody is suggesting anyone call their mom if they hate her guts.

In this case, looking at the actual words can help one to understand why other people interpreted the statement differently than they did.
