6 Dangerous postcards trapped in an Envelope

Send 6 pcs, store bought, good condition, to your partner, denoting dangerous scenes. Use poetic licence and a sense of humour, no sourpusses need to join.

Send tigers, tanks, jetfighters, sheep, you don't think sheep are dangerous? Ever fallen over one in the dark? Think outside the normal there are volcanoes, heavy seas, sand (so you have never had it blown in your eye and had to wear an eyepatch for 3 days. I have.), snow (again you have never seen me ski), snakes, birds (got bitten by a hen once) or maybe a ladder (fell off one of those). You get the idea. Be careful when you seal that envelope.

Might be best if you include a note stating why your postcards are dangerous. Some hazards are not always obvious.
