UM... unaccompanied mothers?

I was sending my mother to the airport. It's just a small but busy airport. It caters rural flights, domestic flights and some regional flights. By regional flights, international destination. I live in a small nation, one can fly to a foreign country under 3 hours.

My mother is quite clumsy when it comes to checking in. Personally, I prefer the self check in kiosk but there is none for this particular airline in this airport. There are 2 self check in kiosk for another airlines, a low cost airline but none for the full service airline. By self check in, I can choose my preferred seat and just drop my luggage at the baggage drop.

Being clumsy, I helped my mother with checking in. So the clerks asked "Who's going?". I replied "My mother...".  "Oh, I thought you're flying along because if so, I need to have a look at you ID" the clerk said. "Nope, just my mum... UM... unaccompanied mother" and then we had a big laugh.

My mother laughed too but a few minutes later, she asked me, "Are you flirting with her?"
"Who?" I asked back.
"The clerk...".
Hey, I just wanted to break the monotony of checking in process. Don't get me wrong. By the way, I'm Libra... always flirting or always seems like flirting. it's in my sign. A Libran always looks flirty even when we don't flirt.
