A late friend who was an author once showed me a drawer full of rejection slips from publishers. He said: " I do not give up because my book was rejected, I keep on sending in my manuscript and sooner or later some publisher will want to print it. All I need is one."

Could always write your name and number on the inside flap of your pack and flash them with it.

I am a full-figured man, but fit. No wedding ring, either. Here I am laughing it up at something or other at Snowy Range in Wyoming last summer.

Memory weighs nothing. Tell him your number. It's his job to keep up with it. If he's genuinely interested he'll put his pack in the snow, while you move efficiently on up the trail. Or set up an email account with an easy to remember name, so he doesn't even have to write it down. Hi, I'm greenfriedtomatoes@blahblah, etc.

my dad had cards that said something like hi my names .... i like chatting arguing drinking etc then his landline number he hated mobiles i lost count of the number of women i met at his house. His rational was women may feel uncomfortable giving their number and they can easily throw away the card later and it only cost him a few quid to get 100 printed

sex...lots of it

However at that early of a stage why do you care about the rejection...I mean the only vulnerability at that point. Chances are you may not see them again unless you carpe diem.
Risk reward equation only you can solve for you?

Thank you, @travelerx2

Great idea! I just attached a pen to my hiking hat brim, and pinned a folded piece of paper under the scarf bow in the back.

Problem solved. Now I need to be more forward.

Have cards printed that say 'International Woman of Mystery'.

I don't know the solution to this problem so when you figure it out could you please let me know

Done the same on the guy side. No real regrets, just wistful what if's to bring a smile around. Try putting pen and paper in your hat ala old reporter style.

A phone weighs, what, 3 oz? "Too heavy" even though it could save your life, never mind get numbers...really?

If you don't need a smart phone get an aftermarket samsung verizon juke. They're not much larger than a lighter. Very zoolander, wonderful little phone. I miss mine. I've a new cherry red one but caved to the "smart phone" vortex ?
I've no words of wisdom on these situations because I'd do the same thing you just described.

Flirting is so difficult. Especillay with all the varied hangups & attitudes people have regarding propriety, monogamy, age, sexual orientation and on and on and on.

I'm naturally very flirty because I enjoy that type of interaction with women who reciprocate. It adds a spark. As a guy I feel I pretty much have to rein it in at all times though, lest I be labeled a letch. I don't know if that's different for woman?
