Flirting in the Grocery Store, i Think...

Today was work from home day for Sir so i tried to keep busy cleaning the second floor, believe me, i didn't even make a dent!

It looks more red in person, lol.

Went to get my hair colored this afternoon, it went much better than last time and the red is really starting to take on the lower part of my hair (where the home dye was).  After i went to the grocery store for just a few things and almost ran into another woman's cart, we laughed it off and went about shopping.  When it came time to check out she was directly in front of me, she turned around and asked if i wanted to go ahead of her since i only have 8 items and she had a full cart, i accepted and thanked her.  While my groceries were being rung up she asked if i had just been at Fantastic Sams getting my hair colored...i told her that i had and she complimented me on the color.  i thanked her and left.  Now here's my question...i haven't been doing this bi thing long so i'm not really sure, and honestly i haven't even dated men since 1984...i'm really out of practice.  i think she was flirting with me, i mean i know those sentences don't sound flirty but the intonation was.  i found her attractive (checked, she wasn't wearing a wedding ring, not that that is scientific) Should i have said or done more?   UGH, i hated dating the first time around and i doubt i'll enjoy it any more this time...Suggestions would be appreciated...how do you KNOW if someone is bi or lesbian?  It's not like it's written on their forehead, nor is it on mine.

#1 is coming over and we're going out for pizza, dropping #4 off to sing on the way.  We have a play party tonight but if #1 has the time and inclination to hang tonight we'll skip it, he has an insane schedule and i wouldn't miss an evening with him.
