What are your superstitions?

That's a new one, loopyloo. I throw salt over my left shoulder, say 'touch wood' and tap my head, no new shoes on the table. When I see a single magpie I always cast about for a second one. When I turn the calendar over for a new month I say 'white rabbits', not that I'm superstitious of course.
Whenever I buy a lotto ticket I ask for a winner but it hasn't worked yet.

New shoes on the table, don't open an umbrella indoors, don't let a black cat cross your path were some of my mum's. I ignore all these, my black cat crosses my path serveral times a day
H greets Magpies with " 'morning major"

New babies always get a coin - this week one of our choir members had her baby grandson with her and 3 of us all donated to his future financial security, which seemed strange, as locally they've never heard of this tradition and I normally have to explain it to the parents. Also when giving a purse or wallet it always contains a £5 note. Shoes on table became a family tradition as my grandfather died very young having put new shoes on the table. Dad always made a hole in the bottom of a boiled egg and turned it upside down to let the witches out, but I've also seen the shell crushed to keep them in - I wonder which is the better option.

Yes all of those as well Auntieflo.
Phoenix is right about fish and Mondays. We always had fish on Friday, although we weren't a Catholic family. My mother saw it as part of being Christian. It's a bit scary how much I recall of the indoctrination isn't it!

Grew up with Mum's superstitions, so if I spill salt, I throw a pinch over my shoulder. Don't put new shoes on a table. Never cross knives. If you give a purse/handbag, there should always be a coin inside. If you receive a knofe as a gift, you should give a small coin to the giver, so you don't sever the friendship. Don't walk under ladders. Don't change the (everlasting) calendat date on 12th to 13th. Etc, etc.

The fish on a Monday thing is not a superstition, it's because it usually wasn't fresh!

I can't leave the house without my phone, now. Something always happens when I don't have it on me.

I don't have any [crossed fingers].

I was brought up by a mother with many superstitions. Salt was thrown over the left shoulder using the right hand if any had been spilled. Poison Ivy, hawthorn blossom, mother in laws tongue etc never to be brought into the house. Never walk under a ladder, have a horseshoe, open end up somewhere in the house or front garden, don't cross on the stairs, if you wash your hands in the sink at the same time as a loved one, spit or you may fall out. Magpies credited with all kinds of magical properties, one for sorrow, two for joy. As with tessagee I could go on but you'll have the picture.

I throw salt over my shoulder if I spill it and knock on wood.

Growing up in an isolated part of Ireland I've got quite a few: a frog or wild bird coming into the house indicates a death in the family is about to happen.

Bluebells, ivy or hawthorn blossom should never be brought indoors and never ever ever cut down a lone hawthorn bush in the middle of a field. The fairies don't like it and you'll bring bad luck on the household.

A horseshoe should be nailed up outside all animal outhouses for protection (always with the open end up).

I could go on and on but you get the gist.

I like to think I am not superstitious, but if I spill salt I will throw a pinch over my left shoulder, and crossing others on stairs is another .

Oh damned Magpies! One for sorrow, two for joy etc.

If I see one Magpie I have to bid "him" good morning/afternoon and ask after his family. My grandchildren giggle and (quite rightly) think I am mad as a hatter.

I don't have any that I know of

Can't think of one
