I feel a little scandalous when eating dinner in a sit-down restaurant by myself. There's something weird about walking in and saying, "just one," and then constantly being approached a little tentatively by the waitress, occasioning an "are you alright?" once or twice.
Maybe I'm not smiling enough. Maybe I look depressed and friendless. But I really just was passing through the neighbourhood on the way from here to there, and happened to be really hungry and in the mood for this particular restaurant. Huh.
