Different Friends

I have this friend. She would be my social director if I let her. We run together, play together, laugh together. In March we're going to Antalya to run a race together (she the half-marathon, me the 10k). Yesterday we spent all day together. It went something like this...
Woke up at friend A's house around 6:30, had nescafe and a nice quiet time (said friend does not wake up until the last minute). Battled snow home, called friend B. Yes, plans are still on. Drank more nescafe - the sign of real laziness - jumped in the shower and headed off to friend B's house. Watched her dig out her car, received a gift, drank espresso, left for lunch with other running friends. After lunch hung out with friends B and C around the Ankara castle area. Bought items for my table in Bozeman (come on, come all!). Separated off from friend C, went to sit a bit more with friend B. While sitting and talking, met up with more of friend B's friends. Said my good-byes (at this point it's 7 pm), went home. Home for 10 minutes when the phone rings. It's friend B. They're at a restaurant near my house. Come, come, come!!! I come. 8:30 pm and a free meal later I'm home and tired.
Said friend B is lovely. She has all kinds of issues, but laughs a lot, loves to talk, and loves to be with friends. And she could easily be my social director if I let her. This is fairly par for the course in a culture where friend groups may be large, but there are not very many of them. Mine are large AND many.
So this morning I shall be alone. I shall not run at the track with friend B - Z from group A. I shall go to the gym. Later today I will hang out with friend A from group B and friend A from group Q. But this morning, I think it's time for this introvert to hang out with...friend Silence.
