Hello, I am still here

What happens when somebody ignores you? may be unintentionally, but it still hurts. There is one person from my workplace, lets say P1. so, P1 always ignores me as if I am not there. when it comes to discuss about work , P1 is very informative and chatty, loves to discuss all scenarios, likes to listen all ideas. but when it is about something else like sharing food or talking about traffic out side, I am totally invisible. Last week there was lots of free food for everybody, yummy muffins & cakes & fruits. P1 told my left neighbor, my right neighbor, my front lady and lady who sits three cubicles in front. BUT not a single word to me. I guess, I became invisible for few seconds. I was not really hungry but its fun to go to cafeteria(once a while). I was sitting there, getting angry, feeling hurt(BTW, invisible people also have feelings). then one thing happened. our(mine and P1's) other team-member told me, specially about vegan food too. and suddenly P1 was all sorry. "oh oh I should have told you. I am sorry. " and blah blah
(I know it will get repeated again as this was not first time.)
I had food with me and I was not that hungry, but what bothers me is P1 forgets (always) I am sitting in next seat.
Anyways, we cant change everything or everybody(and some people are always..........)

Thanksgiving is next week. Hope everybody will be thankful about something they did or they did not.........
