The UVic Writer's Guide
Do not use like if as or as if will work. "She acts as if we had never met" is preferable to
"She acts like we never met."
Technically, like is a preposition ("Shirley looks like Suzanne"), and therefore
should not introduce a clause; as is a conjunction, and is perfectly happy doing so.
