I've always been a native English speaker, but my first 11 years of education weren't in the U.S. I also don't have an issue with: their, there, and they're.
Affect and effect were tough for me, though. I still have to think about it for a moment
And slightly off topic, I still can't tell the difference between pansexual and bisexual. Each time I feel like I have a decent internal definition someone comes along to inform me that I've got it wrong
I'm a woman in the U.S. and I've never had a friend ditch a guy for using a different phone than them.
This is either fake, limited to the younger generation, infrequent enough that I've never encountered it, or regional
I know men who have a hard time getting dates, but phone choice has never been brought up as to why they're rejected
(Frankly, if someone rejects anyone for what phone they are using, the rejecting-party's clearly not worth pursuing)
