Kiss Of The Doppelganger

I wasn't the one who encountered it but I'm involved in this one so here it goes...

This happened during my college days year 2010, I took a leave from school because my grand mother passed away and we have to travel to Isabela that time. I'm always keeping in touch with my friends in school to know what did I missed from our lessons and activities. After a week, my friends were glad to see me again and we are inside our gymnasium for our P.E Class, after asking how Am I and my mom coping up with our lost they asked me when did I arrive, I told them that I arrived only yesterday then two of my friends look at each other and told me what happened.

My friend Abby (not her real name) told me that Ammy (not her real name as well) and her family saw me in Robinson's Imus last Friday night. Ammy says her mom asked me what Am I doing there and I answered her mom that I'm doing shopping and that I even kissed her younger sister before saying goodbye.

I told them that it's impossible because I was in Isabela that time with my family because of what happened to my grand mother and SM Pala Pala or Walter mart is more convenient for me to go shopping than Robinson's Imus and besides there's Robinson's Pala-Pala which is near to my place than Imus. They asked me who did they just saw in Imus, my other friend thought that maybe it's a doppelganger and Ammy freaked out because it kissed her sister.

And until now, the question 'why me?' still pops up whenever I think of that incident, is it because I was not in Cavite that time? It really bothers me tho.
