When my Uncle Eric passed away six years ago, we had to clean out his place. I took two of his sweat pants, his work jacket which had his name on it (he had his own company before he got sick) and his sweatshirt. I wear them to this day and it makes me closer to him. His work jacket is stained and torn, not in the best of shape. His sweatshirt is paint stained. Do whatever you need to do to knock some sense into this jackass roommate of yours and proudly wear your father's sweater.

What a strange thing to keep. What next, the last plate he ate off?

This is why people I date and am friends with know which things not to touch. I usually keep mementos from deceased/favored family members in a box, but there are a few items that I have out.

... You wear the sweater your father died in?

Not necessarily.

#6 you'd be surprised, some are just clueless and forgetful.

to clear things up, i do not know what he wore when he actually passed (hopefully he wasn't naked #26). However I'd spent the weekend with him and he passed suddenly the day after I left. He wore that sweater over the weekend, thus to me it's the last thing he wore. #40, it might seem like a strange thing to keep but we all associate different things with different memories.

if they thought it was so ugly why would they wear it in the first place.

Hope you told him that so he stfu.

If the sweater was ugly, now it was ugly when your dad wore it too. Tell your partner doesn't matter if the sweater is ugly or not, it's important to you. Sometimes when people we love pass away, their personal items help us to deal with loss. If you don't want your partner to wear/ make fun of, you could always pack the sweater away.
