Firstly let be clear I did politely thank the sender, I'm not terrible. But I was sent flowers in the post yesterday and my only reaction was annoyance.
I don't own a vase so had to find a jug big enough for them. Loads of random wrapping that makes a big mess, loads of water in the wrapping that I didn't know about so flooded the table, spilt half the packet of the food liquid stuff which is very sticky, couldn't cut through the thick stems with first pair of scissors and had to use a knife.
Then they last a little while and don't even look that nice, and once they are past their best there's smelly, slimy water to deal with a drippy bunch of dead plant matter to chuck away.
I would happily never be sent or given flowers ever again. Just me or anyone else not like them?
