I was once in a store, going along with my trolley when a lady backed away from a shelf without looking behind her. I couldn't prevent my trolley from getting her foot and although it was her fault not mine, I gave her the customary apology, two in fact. I asked if there was anything I could do. She ignored me, grabbed her foot and groaned before limping off. I felt quite guilty.
5 minutes later i passed her again. This time she was walking fine. Zooming around without a care in the world and having no trouble carrying a giant clay urn to her trolley. Then she saw me, slowed down, started to limp and gave another groan before stooping to cradle her foot again. Suspecting a bit of theatrics going on, I carried on shopping. As I queued at the tills later I happened to glance around and saw her standing at the adjacent queue, staring at me. As soon as she saw me looking at her she gave another "ouch" and bent down to tend to her foot looking up at me in intervals.
Was she laying a guilt trip or what?
