Devils advocate:

If you're known as a guy that loves Pokémon cards and people keep gifting you Weedle's (one of the lowest powered and most common cards in the game), then after a while you're going to be like "thanks guys, I know you want to gift me and to not just throw the card away, but these are worth literally nothing to me because I already have much nicer examples and I don't need/want/have room for them, I'd just be throwing them away myself".
