You decide to come back to the bodega the next day.

And the next day.

And the next day.

And every few days, so does the girl.

And every time, you two have the same routine. She gets her sandwich, feeds you, and you two eventually start to play together. You get friendlier and friendlier each time she comes to visit, and you begin to look forward to your trip each day, and if this will be one of the days you'll see her, and remember you have it to look forward to on the harder days or when the gaps between visits get longer.

And one day, during your routine, she decides that you will now be a permanent part of her life instead of making this a visit every couple of days.
