bear in mind 

Officially means: "To remember, think about, or consider someone or something (in regard to something else)"
However, it is often used in conjunction with the phrase: "Thank you, I'll bear that in mind" to express that actually you won't do that and it is a way to avoid exploding towards a remark someone has made.

Sally: "Just for future reference don't use the term 'man' as it is offensive
Steve: "Thank you, I'll bear in mind."

bear in mind 

Due to the unfettering threat of bear attacks - stemmed by one Mr. Stephen Colbert - it is an idiom that suggests one should be mindful of there surroundings, especially when one ventures into known bear territory (Note: Terra Firma is considered bear territory).

This phrase can intrinsically refer to Melissophobia as well.

Suzy: "You wanna go on a hike up Blood Mountain?"

Trevor: "I'd love too! We should bear in mind the dangers of hiking that mountain though."

Suzy: "Bear in mind what dan-"

*Out of nowhere, a black bear (ninja bear) mauls Suzy to death. Trevor is speechless. . . but goes on the hike anyways. The End.*
