Dear redditors,

Long-time lurker first real TIFU. This one happened yesterday...

My wifes' 93 year old grandmother is currently in the hospital, recovering from pneumonia. As it's New Years the whole family goes to visit, to wish her the best.

When we arrive, my father, mother, brother and uncle in law are already in the room and with little spare seating, I sit down on the only free chair left, next to my brother-in-law at the end of grannys' bed. 

It's a very regular visit, everyone exchanges wishes, hands granny her presents and we're all just chatting away. After about an hour or so i get bored take out my cell and start redditing. 

All of a sudden there's some movement in front of me and I glance up from my phone. Apparently granny needed to pee and I was just in time to see granny pull away her blankets and sitting up on her bed. Granny went commando under her nightgown and I had front seats and, being the moron I am, I let out a grunt. Whole family of in-laws looks at me and realizes the sight i just had. Everyone embarrassed except for granny who just moves on to the bathroom.

Rest of the family gathering was pretty quiet. We stayed like another half an hour staring awkwardly at each other. Upon leaving the hospital my brother-in-law leans in and said: "sorry man, But if it makes you feel better i saw it too..." 

Wife hasn't said a word about it so far
