I once texted my husband (called James) to tell him I was going to have a meal with another friend James at the end of a day in London visiting various peeps. The text, rather than saying "Going for a meal with James" said "Going for a neck with James" and I didn't notice it before I sent it!
My sister's name is Anna and if she signs off a text with "Love" and her name it becomes "Love Bomb".
