Don't be surprised

My favourite item is old and torn,
it's a grey jersey to keep me warm.
I'll wear it despite how faded and worn,
it looks so plain without any charm.

If you come over for a cup of tea,
don't be surprised!

I'll serve you wearing my old jersey,
it's more precious than a costly attire.
Well, it makes me look untidy and lousy,
but I wish to have it till I retire.

If I die and I'm placed in a coffin box,
don't be surprised!

Maybe I'll be wearing my old jersey,
buried with sentimental value.
Laid to rest on a beautiful day,
departing with no style and hue.

If you see me wearing my old jersey,
don't be surprised!
