Definition: In this task, you are given a Reddit post as a text. Your task is to generate a title for this text. The title should start with "TIFU by", followed by a situation that caused humor. The title should contain 7-12 words, ideally.
Input: Text: so, me (37m) and my best friend (47f) really are the best of mates, and have been for about 15 years.

we know what we're each thinking most of the time - we not only finish each others sentences, we also start them.  it's like that.

each of us also has quite a wicked sense of humour.

we know each other too well though, so when one of us has thought of something that we think is either really funny or really upsetting, we know the other lets out a little 'tell'.  in my case my 'tell' for 'funny' is a little self-satisfied smirk, 'upset' is a glazed look.  in her case it's either a little smirk where she looks away from me to stifle a smile, or the fact that she's switched off completely from whatever i was saying and she wants to talk to me about something important.

these facts are important, because today we had a couple of 'tells' in a row:

-i realised she was switching off, so my brain went elsewhere for a bit

-when she came to, she realised i was smirking a little

which is why, when challenged, i came out with this:

"usually when your head is bleeding and you're unconscious, i roll you so you're on your front.  this 'recovery position' isn't doing anything for me".

turns out a corporate sponsored first aid course, with 12 of our colleagues present, is probably not the time to make a comment like that.

TIFU by making a joke that with hindsight may have crossed a slight line for everyone
