<p>*“two ways in which” is better than “two ways that that”.</p>
<p>that that it totally fine i think. i’ve noticed that in places where I would write ‘that that’ authors simply shorten it to ‘that’, and it actually kind of seems to work. ‘in which’ is not fun to read.</p>
<p>I can’t stand when people misuse they’re/their/there. Same thing goes for it’s/its. It’s really not that complicated! Oh, and when people interchange bored with board and loose with lose. I also hate when people spell grammar as “grammer” and receive as “recieve”.</p>
